| Abstract Scope |
Large quantities of selenium (Se)-containing wastewater are generated by the coal mining process. Therefore, it is urgent to treat wastewater containing low concentrations of Se. In this study, MIL-101-NH2 was synthesized by a hydrothermal method, and the effects of parameters, such as pH and contact time on the removal of Se(IV) were evaluated. The adsorption kinetics of MIL-101-NH2 on Se(IV) were evaluated using pseudo-first-order and pseudo-second-order models. Langmuir and Freundlich models were used to analyze the equilibrium isotherms of the system. The maximum adsorption was 32.289 mg/g according to the Langmuir model. The results showed that the removal efficiency of Se(IV) by MIL-101-NH2 was 75.96% at pH = 6 and adsorption time = 3 hours. This study demonstrated that MIL-101-NH2 has great potential for wastewater treatment. |
