For a rapid electron transfer process which follows a reversible chemical step (CE), an analysis procedure is presented for the determination of chemical and electrochemical parameters. It is based on methods of convolution electrochemistry and can be applied to chronoamperometric curves. The main equations of the reported procedure are very simple and are easily analyzed. The analysis procedure has been applied to both simulated and experimental data. As an experimental example, the electroreduction of Cd+2 in DMF containing 0.5 M TEAP at 25 degreesC was investigated.
