摘要: 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膨润土对模拟含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膨润土对废水中的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

Abstract: Experimental study was made on adsorbing Pb2+,Ni2+ and Cd2+  from the simulated waste water by using natural Ca-betonite and modified betonite produced by a betonite factory in Yongquan,Weifang,Shandong respectively. The results show that the natural Ca- betonite and modified betonite produced by this betonite factory have high removal rates of Pb2+,Ni2+ and Cd2+  in the waste water and therefore,can be used as the absorbent for heavy metal ions of Pb2+,Ni2+ and Cd2+.

Key words: Betonite and modified betonite, Waste water, Heavy metal ions, Pb2+, Ni2+ and Cd2+
