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。Abstract: 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.
