不同粘土处理水中重金属的性能研究

Study on different clays as adsorbents in heavy metals-containing wastewater treatment

比较了膨润土、高岭土、伊利石等不同粘土对处理重金属离子的效能，探讨了3种粘土去除废水中镍、铜、锌、镉的适宜条件，并对3种粘土去除重金属离子的机理进行了初步探讨。应用于电镀废水中重金属离子的处理，效果良好。

Different clays such as bentonite, kaoline and illite were ued to absorb Ni, Cu, Zn, Cd in water.The adsorption capacities and the optimal adsorption conditions were examined in detail. The structure of clays and mechanism for their adsorption were studied. As a practical usage, the bentonite was applied to treat the electroplation wastewater and the result was good.
