Carrier-mediated transport of toxic elements throguh liquid membranes Transport of Cd(II) from high salinity chloride medium through supported liquid membrane containing TBP/cyclohexane

摘要

The transport of divalent cadmium ions from high salinity chloride medium SLM containing TBP in cyclohexane supported on cellulose acetate membrane into a strip solution with EDTA has been studied. Permeability coefficients of metal ions a strip solution with EDTA has been studied. Permeability coefficients of metal ions increased with increasing the pH of feed from 1-4. It also increases with increasing with increasing membrane and strip concentrations. At higher concentrations of TBP in themembrane, metal transport was faster, further increase in TBP concentrations up to 80-100/100 (v/v), the metal transport slowed down.
