L-Glutathione-Functionalized Silica Adsorbent for the Removal of Pesticide Malathion from Aqueous Solutions

نویسندگان

چکیده

An L-glutathione-functionalized silica adsorbent was applied in this study to remove malathion from aqueous media. This has demonstrated an improved adsorption efficiency of malathion. The maximum uptake achieved 130 mg g?1 at pH 8. Equilibrium reached after about 90 min. A pseudo-second-order model best described the kinetics. isotherms were simulated by Freundlich model. functional groups are thermally stable up 150 °C. elemental analysis results indicated high glutathione ligand densities. show that environmentally friendly L-glutathione functionalized is a promising candidate for removal water industrial level.

Nanocrystalline Akaganeite as Adsorbent for Surfactant Removal from Aqueous Solutions

The present study presents the effective use of nanocrystalline akaganeite for the adsorption of an anionic (SDS), a cationic (CTAB), and a nonionic (tween80) surfactant from wastewater. Equilibrium experiments, as well as thermodynamic analysis, were performed. The maximum SDS adsorption occurs at the lowest pH value (5), the opposite is observed for CTAB (pH = 11), while for tween80, the chan...

Mercury removal from aqueous solutions by palm leaves adsorbent

Mercury is a carcinogenic and teratogenic compound that tends to accumulate in water solutions. In this research, the removal of mercury from an aqueous solution was evaluated by using palm leaves. Experiments were performed to study the adsorption efficiency, the effect of the adsorbent amount, the balance time, the adsorbate concentration, and the pH on mercury removal. The experimental appar...
