Abstract
2-Mercaptobenzothiazole was used as a highly selective and efficient carrier for the uphill transport of silver ion through a chloroform bulk liquid membrane. In the presence of thiosulfate ion as a suitable metal ion acceptor in the receiving phase, the amount of silver transported across the liquid membrane after 180 min was 90 ± 3.0%. The selectivity and efficiency of silver ion transported from aqueous solutions containing equimolar mixtures of Zn2+, Cu2+, Co2+, Ni2+, Cd2+, Pb2+, Bi3+, Fe2+, Fe3+, Pd2+, Mn2+, Hg2+, Sn2+, Ca2+, Mg2+, K+, Na+ and Li+ were investigated.
