Abstract: The precipitation of Chromium(III), copper(II), manganese(II) and zinc(II) by biogenic hydrogen sulfide generated by sulfate-reducing bacteria. Desulfovibrio sp., and the degradation of total petroleum hydrocarbons (TPH) in the presence of heavy metal by Pseudomonas aeruginosa AT18 have been carried out. An anaerobic stirred tank reactor was used to generate hydrogen sulfide with Desulfovibrio sp. culture and the precipitation of more than 95% of each metal was achieved in 24 h (metal solutions contained: 60, 49, 50 and 80 mg L-1 of chromium, copper, manganese and zinc sulfates). A stirred tank reactor with P. aeruginosa AT18, in the presence of the heavy metal solution and 2% (v/v) of petroleum. led to the degradation of 60% of the total petroleum hydrocarbons and the removal of Cr(III) 99%, Cu(II) 93%. Zn(II) 46% and Mn(II) 88% in the medium through biosorption phenomena. These results enabled the development of an integrated system in which the two processes were combined. The overall aim of the study was achieved, with 84% of TPH degraded and all of the metals completely removed. Work is currently underway aimed at improving this system (decrease in operation time, culture of P. aeruginosa in anaerobic conditions) in an effort to apply this process in the bioremediation of natural media contaminated with heavy metals and petroleum.

Abstract: A molecularly imprinted TiO₂ film was constructed onto the surface of a TiO₂ nanotube (NT) array, getting a novel composite TiO₂ catalyst. Compared with unmodified TiO₂ NT and the non-imprinted film modified TiO₂ NT, the molecularly imprinted film modified TiO₂ NT not only exhibits a much higher adsorption capacity for the target contaminant but also shows an enhanced photocatalytic activity in degrading the target contaminant. Moreover, the molecularly imprinted inorganic semiconductor film is not degraded during photocatalysis, owing to its stable physicochemical properties which is superior to those of conventional molecularly imprinted organic polymer films.

Abstract: This communication challenges the concept that nanoscale metallic iron (nano-Fe-0) is a strong reducing agents for contaminant reductive transformation. It is shown that the inherent relationship between contaminant removal and Fe-0 oxidative dissolution which is conventionally attributed to contaminant reduction by nano-Fe-0 (direct reduction) could equally be attributed to contaminant removal by adsorption and co-precipitation. For reducible contaminants, indirect reduction by adsorbed Fe-II or adsorbed H produced by corroding iron (indirect reduction) is even a more probable reaction path. As a result, the contaminant removal efficiency is strongly dependent on the extent of iron corrosion which is larger for nano-Fe-0 than for micro-Fe-0 in the short term. However, because of the increased reactivity, nano-Fe-0 will deplete in the short term. No more source of reducing agents (Fe-II, H and H-2) will be available in the system. Therefore, the efficiency of nano-Fe-0 as a reducing agent for environmental remediation is yet to be demonstrated. (c) 2010 Elsevier By. All rights reserved.

Abstract: This work focused on kinetic, equilibrium and thermodynamic studies on aluminum biosorption by Streptomyces rimosus biomass. Infrared spectroscopy analysis shows that S. rimosus present some groups: hydroxyl, methyl, carboxyl, amine, thiol and phosphate. The maximum biosorption capacity of S. rimosus biomass was found to be 11.76 mg g^-1 for the following optimum conditions: particle size, [250-560] mu m, pH 4-4.25, biomass content of 25 g L^-1, agitation of 250 rpm and temperature of 25ºC. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) models were applied to describe the biosorption isotherms at free pH (pH(i) 4) and fixed pH (pH(f) 4). Langmuir model is the most adequate. With fixed pH, the maximum biosorption capacity is enhanced from 6.62 mg g^-1 to 11.76 mg g^-1. The thermodynamic parameters (G°, H° and S°) showed the feasibility, endothermic and spontaneous nature of the biosorption at 10-80ºC. The activation energy (Ea) was determined as 52.18 kJ mol^-1 using the Arrhenius equation and the rate constant of pseudo-second-order model (the most adequate kinetic model). The mean free energy was calculated as 12.91 kJ mol^-1 using the D-R isotherm model. The mechanism of Al(III) biosorption on S. rimosus could be a chemical ion exchange and carboxyl groups are mainly involved in this mechanism. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: The synthetic imogolite sample was used for organofunctionalization process with 2-mercaptothiazoline (MTZ). The compound 2-mercaptothiazoline was anchored onto imogolite surface by heterogeneous route. Due to the increment of basic centers attached to the pendant chains the dye adsorption capability of the final chelating material, was found to be higher than is precursor. The ability of these materials to remove methylene blue from aqueous solution was followed by a series of adsorption isotherms at room temperature and pH 4.0. The maximum number of moles adsorbed was determined to be 40.32 x 10(-2) and 65.13 x 10(-2) mmol g(-1) for IMO and IMOMTZ, respectively. The energetic effects caused by dye cations adsorption were determined through calorimetric titrations. Thermodynamics indicated the existence of favorable conditions for such methylene blue-nitrogen and sulfur interactions. (C) 2010 Published by Elsevier B.V.

Full Text: 2010\J Haz Mat183, 87.pdf

Abstract: Unlike hydrophobic organic pollutants, the potential of organoclays to adsorb inorganic ionic contaminants is relatively underexplored. The present study attempts to characterise bentonite (QB) based organoclays synthesised from a commercially available, low-cost alkyl ammonium surfactant Arquad (R) 2HT-75 (Aq) and test their ability to adsorb hexavalent chromium (Cr(VI)) in aqueous solution. XRD, FTIR and TGA characterisation techniques prove successful modification of the bentonite structure and reveal that higher surfactant loadings gives rise to more ordered surfactant conformation in the organoclays. The zeta potential values indicate that higher surfactant loadings also create positive charges on the organoclay surfaces. Detailed isothermal and kinetic studies show that the organoclays effectively remove hexavalent chromium (Cr(VI)) from aqueous solution by both physical and chemical adsorption processes. Higher surfactant loadings provide better adsorption efficiency. The adsorption performance is reasonably efficient under the levels of pH, temperature, electrolyte concentration and natural organic matter concentration that generally prevail in contaminated soil and water. This study shows that organoclay sorbents offer good potential for remediating Cr(VI) under real environmental conditions. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: In this paper, different starches were modified by diethylenetriamine. The native starch reacted with diethylenetriamine giving CAS, whereas the enzymatic hydrolysis starch was modified by diethylenetriamine producing CAES. Adsorption capacities of CAES for four acid dyes, namely. Acid orange 7 (AO7). Acid orange 10 (AO10), Acid green 25 (AG25) and Acid red 18 (AR18) have been determined to be 2.521, 1.242, 1.798 and 1.570 mmol g^-1, respectively. In all cases. CAES has exhibited higher sorption ability than CAS, and the increment for these dyes took the sequence of AO7 (0.944 mmol g^-1) > AO10 (0.592 mmol g^-1) > AR18 (0.411 mmol g^-1) > AG25 (0.047 mmol g^-1). Sorption kinetics and isotherms analysis showed that these sorption processes were better fitted to pseudo-second-order equation and Langmuir equation. Chemical sorption mechanisms were confirmed by studying the effects of pH, ionic strength and hydrogen bonding. Thermodynamic parameters of these dyes onto CAES and CAS were also observed and it indicated that these sorption processes were exothermic and spontaneous in nature. (C) 2010 Elsevier B.V.

Abstract: In this study, chitosan (CTS) was crosslinked with both epichlorohydrin (ECH) and triphosphate (TPP), by covalent and ionic crosslinking, respectively. The resulting new CTS-ECH-TPP adsorbent was characterized by CHN analysis, EDS. FTIR spectroscopy, TGA and DSC, and the adsorption and desorption of Cu(II), Cd(II) and Pb(II) ions in aqueous solution were investigated. Potentiometric studies were also performed and revealed three titratable protons for each pK(d) value of 5.14, 6.76 and 9.08. The results obtained showed that the optimum pH values for adsorption were 6.0 for Cu(II), 7.0 for Cd(II) and 5.0 for Pb(II). The kinetics study demonstrated that the adsorption process proceeded according to the pseudo-second-order model. Three isotherm models (Langmuir, Freundlich and Dubinin-Radushkevich) were employed in the analysis of the adsorption equilibrium data. The Langmuir model resulted in the best fit and the new adsorbent had maximum adsorption capacities for Cu(II), Cd(II) and Pb(II) ions of 130.72, 83.75 and 166.94 mg g^-1 respectively. Desorption studies revealed that HNO₃ and HCI were the best eluents for desorption of Cu(II), Cd(II) and Pb(II) ions from the crosslinked chitosan. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: Sorption and combined sorption-biodegradation experiments were conducted in laboratory batch studies with 100g soil/sediments and 500 mL water to investigate the fates in aqueous environments of acetaminophen, caffeine, propranolol, and acebutolol, four frequently used and often-detected pharmaceuticals. All four compounds have demonstrated significant potential for degradation and sorption in natural aqueous systems. For acetaminophen, biodegradation was found to be a primary mechanism for degradation, with a half-life (t(1/2)) for combined sorption-biodegradation of 2.1 days; in contrast, sorption alone was responsible only for a 30% loss of aqueous-phase acetaminophen after 15 days. For caffeine, both biodegradation and sorption were important (t(1/2) for combined sorption-biodegradation was 1.5 days). However, for propranolol and acebutolol, sorption was found to be the most significant removal mechanism and was not affected by biodegradation. Desorption experiments revealed that the sorption process was mostly irreversible. High values were found for K-d for caffeine, propranolol, and acebutolol, ranging from 250 to 1900 L kg(-1), which explained their greater tendency for sorption onto sediments, compared to the more hydrophilic acetaminophen. Experimentally derived values for log K-oc differed markedly from values calculated from correlation equations. This discrepancy was attributed to the fact that these equations are well suited for hydrophobic interactions but may fail to predict the sorption of polar and ionic compounds. These results suggest that mechanisms other than hydrophobic interactions played an important role in the sorption process. (C) 2010 Elsevier B.V. All rights reserved.

Full Text: 2010\J Haz Mat183, 256.pdf

Abstract: Cadmium uptake by activated sludge was studied following modifications of sludge composition and surface properties induced by ozone treatment. Ozone leads to the solubilization of sludge compounds as well as their mineralization, especially humic like substances. Small particles were formed following floc disintegration, leading to a decrease of average floc size. The study of surface properties underlined the mineralization as the number of surface binding sites decreased with the increase of ozone dose. Depending on ozone dose, cadmium uptake by activated sludge flocs was either increased or decreased. Different mechanisms were involved: below 10 mg O-3/g TS, the increase of floc specific surface area following floc size decrease as well as the release of phosphate ions yielded an increase by 75% of cadmium uptake, due to the better availability of biosorption sites and the increase of precipitation. Inversely, at higher ozone doses, the number of biosorption sites decreased due to oxidation by ozone. Moreover, dissolved organic matter concentration increased and provided ligands for metal complexation. Cadmium uptake was therefore limited for ozone doses ranging from 10 to 16.8 mg O-3/gTS.

Abstract: The Guangzhou section of the Pearl River (GSPR) has been seriously affected by long-term intensive industrial and urban activities. The objectives of this study were to determine the total As (TAs) content and the forms of that As in order to investigate the geochemical relationships between As forms and sediment mineral phases of the surface sediments of the GSPR. Fifteen samples of surface sediment were collected and analyzed for TAs as well as As chemical forms. Results indicated that TAs in the sediment samples averaged 24.6 mg kg(-1) and ranged from 16.7 to 33.4 mg kg(-1). These values are generally higher than the probable effect level of 17.0 mg kg(-1). The As was mostly associated with iron oxides (53.5%), followed by association with the residual fraction (36.2%). Amor-Fe bound As and Cry-Fe bound As quantities were positively correlated to the Amor-Fe and Cry-Fe quantities, respectively. In addition, organic matter(OM), clay and Sum-Fe contents were positively correlated to TAs in the sediment fractions. The molar ratios of iron oxide-bound As to iron content approached the maximum molar ratios of As to Fe for natural hematite, magnetite, and goethite. Adverse effects caused by As will likely frequently occur at these high levels of As contamination. Thus, it is necessary to remediate the sediment of the GSPR to reduce the potential risks of As contamination. (C) 2010 Elsevier B.V. All rights reserved.

Abstract: The catalytic ozonation of fenofibric acid was studied using activated alumina and alumina-supported manganese oxide in a semicontinuous reactor. The rate constants at 20 degrees C for the non-catalytic reaction of fenofibric acid with ozone and hydroxyl radicals were 3.43 +/- 0.20 M-1 s(-1) and (6.55 +/- 0.33) x 10(9) M-1 s(-1), respectively. The kinetic constant for the catalytic reaction between fenofibric acid and hydroxyl radicals did not differ significantly from that of homogeneous zonation, either using Al2O3 or MnOx/Al2O3. The results showed a considerable increase in the generation of hydroxyl radicals clue to the use of catalysts even in the case of catalytic runs performed using a real wastewater matrix. Both catalysts promoted the decomposition of ozone in homogeneous phase, but the higher production of hydroxyl radicals corresponded to the catalyst with more activity in terms of ozone decomposition. We did not find evidence of the catalysts having any effect on rate constants, which suggests that the reaction may not involve the adsorption of organics on catalyst surface. (C) 2010 Elsevier B.V.

Abstract: The removal of natural organic matter (NOM) by coagulation and adsorption on modified wheat straw (MWS) was investigated. Two types of inorganic polymer coagulants, polyferric chloride (PFC) and polyaluminum chloride (PAC), were used during experiments. The removal efficiency of NOM in terms of UV254, DOC and CODMn increased with the dosage of coagulants and adsorbent increasing. Combined coagulation and adsorption showed better UV254 and turbidity removal efficiency (61.8% and 95.8% respectively for PFC-MWS, and 61.5% and 94.2% respectively for PAC-MWS) than individual treatment. The effects of combination sequences on DOC fractionation and residual chlorine decay were analyzed and the chlorine data were fitted using a chlorine decay model. In general, the higher the molecular weight of NOM was, the better removal efficiency the combined treatment can achieve. MWS can enhance the removal of NOM with higher molecular weight. The disinfection by-products (DBPs) formation potential in the effluents from coagulation and subsequent adsorption was greater than that in the effluents from adsorption and subsequent coagulation.
