【Abstract】 In this paper the equation of adsorption-complex wave in differential pulse polarography is described.According to the reaction scheme M+xL■ML_x ML_x■（ML_x）_ads （ML_x）_ads■（NL_x）_ads （NL_x）_ads■NL_x the current controlled by both adsorption and diffusion obeys the following equation: i=0.412nFm^2/3t₁^2/3D^1/2C_M^*(1/δ^1/2)·（ξ（θ₁-θ₂）/（1+ξθ₂）（1+ξθ₁））·（θ₁-θ₂）/（1+θ₁）（1+θ₂） where θ₁=exp（nF/RT）（E₁-E⁰） θ₂=exp（nF/RT）（E₁-E⁰+△E） ξ=b_MLxΓ_MLx■m/b_NLxΓ_NLx,m Experiments were carried out on a pulse polarograph to verify the theory. The theoretical conclusion is in good agreement with experimental data for the reduction of U（Ⅵ） in 0.1M HOAc-0.1M NaOAc-0.001% Cupferron solution.更多还原
