摘　　要：重金属离子的绿色高效去除技术一直是环境科学领域的研究重点。采用机械力化学法通过添加MgSO_(4)制备了云母基环境功能材料,并考察了其对溶液中Cd(Ⅱ)的吸附性能。研究结果表明,采用行星式球磨机,在600 r/min转速下共磨云母原样和MgSO_(4)颗粒1 h即可得到该云母基吸附材料。当其用量为5 g/L时,处理Cd(Ⅱ)初始质量浓度为100 mg/L、pH为6的溶液,Cd(Ⅱ)吸附率可达87.79%。溶液中的Cd(Ⅱ)通过与Mg(Ⅱ)交换而被吸附固定在材料中。该研究为云母基矿物材料的制备提供了一条新的路径。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 MgSO_(4),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 MgSO_(4) 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.
