天然斜发沸石吸附废水中Pb^(2+)、Cd^(2+)、Ni^(2+)、Zn^(2+)的试验研究

Experimental Study on the Adsorption of Pb^(2+),Cd^(2+),Ni^(2+) and Zn^(2+) from Wastewater by Natural Clinoptilolite

用山东潍坊涌泉天然斜发沸石对模拟含重金属离子Pb2+、Cd2+、Ni2+、Zn2+的废水分别进行了试验研究。结果表明,该地天然斜发沸石对废水中的Pb2+有较高的去除率,可以作为重金属离子Pb2+的吸附剂使用。

The experiment was made on using Yongquan natural clinoptilolite produced in Weifang, Shandong Province to remove the heavy metal ions such as Pb^2＋, Cd^2＋, Ni^2＋ and Zn^2＋ from a simulated wastewater. The result indicates that this natural clinoptilolite has high removal rate of Pb^2＋ in the wastewater and can be used as an absorbent for Pb^2＋.
