“…The values of ∆Gº were negative at various temperatures and decreased with the increase in temperature, showing that the adsorption was spontaneous and easier at higher temperatures [41]. The positive values of ∆Hº indicated that the adsorption process was endothermic.…”

“…As shown in Fig. 7, the loading capacity of MnSb increases with increasing initial ion concentrations, since the initial concentration provides the necessary driving force to conquer the resistance to the mass transfer of ions between the solution and adsorbent [29,41]. In addition, the uptake of cobalt is obviously greater than that of strontium.…”

BACKGROUND Microalgae which have greater biodegradable fractions than other organics were chosen as a carbon source for sulfate‐reducing bacteria (SRB). Immobilized SRB–microalgae beads were then prepared and used for bioremediation of synthetic copper mine wastewater. RESULTS Hydrolysis fermentation of the microalgae was observed and it was noted that the microalgae were first degraded to volatile fatty acids by co‐existing fermentative bacteria; they then served as a carbon source for SRB. Freshly prepared immobilized SRB beads not only possessed high mechanical strength and mass transfer ability, but also showed better sulfate reduction than that of suspended SRB. Immobilized SRB‐Scenedesmus obliquus beads packed in the upflow bioreactor were suitable for the treatment of copper mine wastewater, as shown by the high removal efficiency of their sulfate (182.17 mg SO42‐ g‐1 microalgae day‐1) and copper ions (45.28 mg Cu2+ g‐1 microalgae day‐1), and low discharge of chemical oxygen demand. After the reaction, metal sulfides were not produced on the bead surfaces, but likely within them. CONCLUSIONS The anaerobic bioreactor, filled with immobilized SRB‐Scenedesmus obliquus beads, demonstrated excellent removal efficiency and low discharge of chemical oxygen demand, which may provide a promising strategy for dealing with heavy metal pollution in water. © 2017 Society of Chemical Industry

“…The competitiveness of adsorbates from ionic interaction and selectivity of the adsorbent (adsorbate charges and radius ions) are the main factors contributing the effect of multi-component adsorption. Since multiple metal ions are more likely to exist in wastewater effluent, various studies have been performed on promising adsorbents for various applications (Akbari et al 2015;Merrikhpour & Jalali 2013;Mohan & Chander 2000;Wang & Li 2009;Xiao & Thomas 2004).…”
