Abstract

Abstract

Green technology for efficient removal of heavy metal ions has always been the focus of environmental science. Mica based materials for environmental applications were prepared by mechanochemical method by adding MgSO₄, and their adsorption properties for Cd(Ⅱ) in solution were investigated. The results showed that the mica-based adsorbent was obtained by co-grinding mica raw material and MgSO₄ particles at 600 r/min for 1 h with a planetary ball mill. At a dosage of 5 g/L, the adsorption rate of Cd(Ⅱ) was reach 87.79% when the initial mass concentration of Cd(Ⅱ) was 100 mg/L and the pH was 6. Cd(Ⅱ) in the solution was adsorbed and fixed in the material by exchange with Mg(Ⅱ). This study provides a novel path for the preparation of mica based mineral materials.
