硫脲型螯合滤膜的制备及其选择性吸附的研究

Preparation of Thiourea Type Chelate Membrane and Study of Selecting Adsorption to Metallic Ion

本文研究了自制的聚砜苄硫脲螫合滤膜对金属离子Ag^+、Hg^(2+)、Cu^(2+)、Fe^(3+)、Pb^(2+)的选择性吸附。探讨了硫脲反应时间、温度、硫脲浓度及盐溶液PH值和盐浓度对选择性的影响,取得了最佳选择条件。

We have prepared chelate nembrane of polysulfonebenzalthiourea and studied the se- lecting adsorption to Ag^+ , Hg^(2+) , Fe^(3+) , Pb^(2+) , Cu^(2+), This paper also studied the effects of thiourea reactive time, temperature, pH of the solution and thiourea concentration on chelate adsorption selectivity. The best condition has been got on select adsorb.
