A spectrophotometric method for the determination of Cd-II in low concentration upto 0.05 mu g ml(-1) after selective extraction of Cd-II. phenanthroline complex on polyurethane foam sorbents using dithizone as counter-ion has been developed. interferences of metal ions such as Mn-II, Ni-II, Co-II, Fe-II upto 100 mu g, Zn-II upto 8000 mu g and Pb-II upto 1000 mu g have automatically been clinlinated in the presence of 1,10-phenanthroline. Cu-II (50 mu g) interferes in the determination of Cd (20 mu g) which has been eliminated by masking with EDTA. F- ion does not interfere in the method. The method Iras been applied to various Zn-bearing materials.
