天然及改性膨润土吸附废水中Pb^(2+)、Ni^(2+)、Cd^(2+)的试验研究

Experimental study on adsorbing the Pb^(2+)、Ni^(2+)、Cd^(2+) from wastewater with natural ca-bentonite and modified ca-bentonite

用山东潍坊涌泉某膨润土厂生产的天然钙基膨润土和改性土,对模拟含Pb2+、Ni2+、Cd2+的废水分别进行了试验研究。结果表明,该厂的天然钙基膨润土和改性土,对废水中的Pb2+、Ni2+、Cd2+有较高的去除率,可以作为重金属离子Pb2+、Ni2+、Cd2+的吸附剂使用。

The effect on absorb the Pb2＋、 Ni2＋、Cd2＋ from wastewater with Ca-bentonite from weifang-yongquan of sandong province were discussed in this paper.Experiments show that natural Ca-bentonite and modified Ca-bentonite can absorb the Pb2＋、 Ni2＋、Cd2＋effectively.
