摘要：

The electrochemical behaviour of some azo compounds of 4-aminoantipyrine derivatives (I-V) have been studied in ethanolic buffered solutions using tast polarography (DC sampled mode), linear sweep and cyclic voltammograms. Generally, the reduction polarograms of these compounds show a single, 4-electrons diffusion controlled irreversible wave within the entire pH range (2-12), which represents the reduction process. The kinetic parameters of the electrode reaction are given.
