| Abstract: | 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. |
