Preparation of Mica Based Adsorbent Through Mechanochemical Activation and Its Adsorption Performance for Cd(Ⅱ)
-
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MgSO4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MgSO4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。
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.
