摘要
蛭石是一种具有优异的吸附、离子交换性能的硅铝酸盐矿物,在环境治理中有广泛的应用前景.介绍了近年来国内外应用天然蛭石在废水处理中的试验研究情况,综述了蛭石在去除水中氨氮、重金属元素、磷酸盐、稀土离子、有机污染物质等方面的应用,并涉及蛭石的活化改性方法,以探求更好的处理效果.
Natural vermiculite is a kind of silicon-alum mineral with high adsorption and selective ion-exchange capability. It is widely used in environmental protection like groundwater and wastewater treatment. Introduce the application to modified vermiculite in water treatment such as the removal of NH3-N, heavy metal ions, phosphate, rare earth metal ions, and organic pollutant. It involves the activation methods of vermiculite for good removal effect.
