Abstract

The transport and separation of Cd(I1) thrcuzlt bulk liquid membrane technique had been investigated and optimised. Cd(ll) was transported through a liquid membrane of chloroform solution containing oxine as mobile carrier and received by EDTA in stripping phase. In compliance with optimum condition. flux of Cd(II) crussing the membrane was studied, and applied further into a model of the transport system and kinetics mechanism. Concentration of Cd(II) in feed and stripping phases were experimentally determined, and monitored by the atomic absorption spectophotometer at λmaks 228,8 nm.The model curve of time dependence of Cd(II) reduced concentrations in the feed, membrane and stripping phases show good agreement and characterized as a transpar, system for Cd(l)) :nterphase invulved two consecutive irreversible first order reactions. The rate constant of transpart at temperature 280C are kl 0.0416 minutes-1, k2 0.0334 minute and activation enemy 32.96 KJ mol-1
