Résumé :

D.c., a.c. and differential pulse polarography and cyclic voltammetry are used to elucidate the electrochemical behaviour of disulfiram. Very strong adsorption phenomena occur, and the electrochemical characteristics of disulfiram are quite different from those of the disulphides studied previously. Changes in the behaviour of the compound as functions of pH and concentration are described. With the differential pulse method, the limit of detection is 5· 10-7 M (0.16 mg l-1 ). © 1976.
