Square-wave voltammetric behavior for uranium(Ⅵ)-cupferron complex was studied in 0.1 M acetate buffer solution(pH5.0). The optimum condition for square-wave voltammetric analysis of uranium was also investigated. The reduction of uranium(Ⅵ)-cupferron complex was found to be irreversible and only uranium(Ⅵ)-cupferron complex was adsorbed on the electrode surface during the deposition time. Detection limit of uranium(Ⅵ) was 7.9nM(2 ppb) where the deposition time was 30sec at -0.1 V vs. Ag/AgCl. The amount of uranium(Ⅵ)-cupferron complex adsorbed on the electrode surface was Γmax = (4.9±0.3) × 10-10 mol·cm-2.
