Yanjun Liu et al.

Summary: Chitosan/bentonite composites (CSBT) were synthesized and used for the immobilization of chromium in the soil. CSBT could reduce the content of exchangeable and oxidizable forms of chromium, while increasing the content of residual form. The addition of 0.2 g.kg(-1) CSBT had the best effect, with the concentration of exchangeable, reducible and oxidizable forms decreased by 46.74%, 8.15%, and 14.46%, respectively. The amino, carboxyl, and hydroxyl groups of CSBT promoted the conversion of available chromium to residual state in soil, and reduced the bioavailability of chromium in soil.

Fast and effective arsenic removal from aqueous solutions by a novel low-cost eggshell byproduct

Ivan Celio Andrade Ribeiro et al.

Summary: This study developed a novel low-cost chemical compound named hydroxyl-eggshell (ES-OH) for arsenic removal from aqueous solutions, providing a local and environmentally-friendly way of recycling eggshells. The adsorption mechanism of ES-OH on arsenic was found to be vladimirite precipitation followed by weak electrostatic interactions, showing promising potential for application in egg-processing industries.

Application of Box-Behnken design for optimizing parameters of hexavalent chromium removal from aqueous solutions using Fe3O4 loaded on activated carbon prepared from alga: Kinetics and equilibrium study

Shirin Afshin et al.

Summary: In this study, the Response Surface Methodology was utilized to optimize the removal efficiency of Hexavalent Chromium using a synthesized adsorbent. The experimental results showed a suitable correlation between the values obtained by experiments and the values predicted by the quadratic model. The study concluded that the efficiency of Cr (VI) adsorption decreased with increasing pH values, while increasing reaction time and adsorbent dosage led to improved process efficiency.

Optimization of Arsenate Adsorption over Aluminum-Impregnated Tea Waste Biochar Using RSM-Central Composite Design and Adsorption Mechanism

Ghazi Mohd Sawood et al.

Summary: Aluminum-impregnated tea waste activated carbon was synthesized and optimized for arsenate adsorption. The adsorbent showed high surface area and excellent uptake capacity, with electrostatic forces and hydrogen bonding playing a role in the adsorption mechanism. The adsorption process followed Langmuir isotherm model and pseudo-second order kinetics, proving to be spontaneous and endothermic.
