摘要
Transport of Ag+ as Ag(CN)(2)(-) ions through a bulk liquid membrane is reported. The bulk liquid membrane used is a solution of Victoria blue (VE) in chloroform. The effects of pH of the source phase, cyanide concentration in the source phase, sodium hydroxide in the receiving phase, and VB concentration in the organic phase on the efficiency of the transport system were studied. The above system has a high selectivity for Ag+ and can selectively and efficiently transport Ag(CN), ion from aqueous solutions containing other cations such as alkali and alkaline earths, Zn2+, Pd2+, Cu2+, Cd2+, Hg2+, Co2+, Fe2+, Pb2+, Ni2+, and Al3+.
