Differential-pulse cathodic stripping voltammetry was applied to the Sn(Ⅱ)-cupferron complex in 0.1 M acetate buffer solution (pH 4.20). Effects of solution pH, ligand concentration, accumulation potential, and accumulation time on the reduction peak current for the adsorptive complex of Sn(Ⅱ)-cupferron were investigated. Interferences by other metal cations that affected on reduction peak current were also discussed. The detection limit was 3.1×10^-9 M (0.37 ppb) of Sn(Ⅱ) with 60 seconds accumulation time. The relative standard deviation (n=8) for 5×10^-8 M Sn(Ⅱ) was 3.0%.
