- Abstract
In recent years, many heavy metal ions have been discharged into the environment, which is threatening human health. Herein, the β-cyclodextrin-modified molybdenum disulfide composite (β-CD/MoS2) was prepared to adsorb Cr(VI) from water. The results demonstrated that the retention of Cr(VI) onto β-CD/MoS2 was dependent on pH and independent of coexisting ions. The removal capacity of β-CD/MoS2 for Cr(VI) reached 156.8 mg/g, and the removal process was endothermic. According to the characterization analysis, the uptake of Cr(VI) onto β-CD/MoS2 was governed by electrostatic attraction. Besides, the oxygen-containing groups were also responsible for the capture of Cr(VI). This work can offer new sight into the uptake of Cr(VI) from the ecological system.
