涌泉膨润土吸附废水中Cu^(2+)、Zn^(2+)、Cr^(3+)的试验研究

Experimental Study on Adsorbing Cu^(2+),Zn^(2+) & Cr^(3+) from Wastewater with Ca-Bentonite

用山东潍坊涌泉某膨润土厂生产的膨润土对模拟含Cu2+、Zn2+、Cr3+的废水进行了试验研究。结果表明,该膨润土对废水中的Cu2+、Zn2+、Cr3+有较高的去除率,并且吸附速度快、时间短,可作为废水中重金属Cu2+、Zn2+、Cr3+的吸附剂使用。吸附后的膨润土,可用作抗菌材料的添加剂。

The effect on absorbing the Cu^2＋、Zn^2＋、Cr^3＋ from wastewater with Ca-bentonite from weifang-yongquan of Sandong province were discussed.Experiments showed this Ca-bentonite can absorb the Cu^2＋、Zn^2＋、Cr^3＋ effectively,after adsorbing the bentonite can be used as additive of antibinsis material.
