“…However, SA was modified into several forms to improve its sorption capacity and mechanical strength. For instance, SA was blended with chitosan [5], humic acid [6], polyurethane [7], cellulose [8], carbon nanotube [9] and soil [10] to enhance the sorption capacity for the removal of heavy metals from aqueous solution.…”

“…Maria K. Doula synthesized a high-surface-area clinoptilolite-iron-oxide system (Clin-Fe) using clinoptilolite, and found that the adsorption capacity of clinoptilolite toward Mn was 7.69 mg/g, while the adsorption capacity of Clin-Fe toward Mn was 27.12 mg/g [55]. Ibrahim M. El-Sherbiny et al [56] combined sodium alginate with different proportions of calcareous soil to form new-composite microparticles (NCM). The removal rate of 0.5-16.0 mg/L Fe by these NCMs was almost 100%, and the removal rate of 0.5 mg/L Mn (II) was about 89% [56].…”

To address the pollution problem of acid mine drainage (AMD) characterized by high concentrations of Fe2+, Mn2+, and SO42−, a combination of coal gangue (CG) and sulfate-reducing bacteria (SRB) was employed. The effects of coal-gangue dosage, SRB inoculation concentration, and temperature on AMD treatment with coal-gangue-loaded SRB were determined through single-factor experiments and response surface methodology (RSM) experiments. By considering the principles of adsorption isotherms, adsorption kinetics, and reduction kinetics, the removal mechanisms of SO42−, Fe2+, and Mn2+ in AMD using coal gangue-loaded SRB in the the Haizhou open-pit mine was revealed. The results showed that the overall effectiveness of the four types of coal-gangue-loaded SRB in repairing AMD was as follows: 3# CG-loaded SRB > 2# CG-loaded SRB > 1# CG-loaded SRB > 4# CG-loaded SRB, with coal-gangue-loaded SRB in the the Haizhou open-pit mine showing the best performance. According to the RSM test, the optimum conditions for repairing AMD with coal-gangue-loaded SRB in the open-pit mine were a coal-gangue dosage of 52 g, SRB inoculation concentration of 11.7%, and temperature of 33.4 °C. The order of factors affecting the removal of SO42− and Fe2+ from AMD by SRB loaded on coal gangue was SRB inoculation concentration > temperature > coal-gangue dosage. For Mn2+, the order of influence was temperature > SRB inoculation concentration > coal-gangue dosage. In the process of repairing Fe2+ with coal-gangue-loaded SRB in the the Haizhou open-pit mine, the biological activity metabolism of SRB played a leading role, while the adsorption isotherm of Mn2+ followed the Freundlich model. The adsorption kinetics of coal-gangue-loaded SRB in the the Haizhou open-pit mine for Fe2+ and Mn2+ in AMD conformed to Lagergren’s second-order kinetic model, while the reduction kinetics of SO42− conformed to a first-order reaction model.

In the recent times, scanty access to clean water has been one of the most prevalent problems, affecting humankind throughout the world. This calls for a tremendous amount of research to recognize new methods of purifying water at lower cost, minimizing the use of hazardous chemicals and impact on the environment. The interest of the scientific community in the potential applications of renewable feedstock-based hydrogels for heavy-metal adsorption for water remediation has been continuously increasing during the last few decades. This study is an effort to highlight the application of hydrogels for revolutionizing the present research on heavy-metal adsorption, particularly arsenic. Besides, the arsenic chemistry, health hazards of arsenic to human health, and adsorption of arsenic by natural polymer-based hydrogels have been reviewed in detail. In addition, challenges in taking the hydrogel technology forward and future prospectives like cost, handling, and disposal of the adsorbent have been discussed systematically.
