Abstract: An equation and its current-potential charaters of differential pulse polarography for reversible waves influenced simultaneously by, the adsorption of both reactant and product are presented and discussed in this paper. The results obtained are the same as those calculated by numerical solution. Teste are carried out to verify the equation by using three systems. The curves described by the theory are in good agreement with the experimental results.
