Basic electrochemical characteristics of 1-benzyl-tetrazole-5-thiol in acid medium were investigated applying classical (DC) polarography, cyclic (CV) and square-wave voltammetry (SWV). During the HMDE life-time, a compound was spontaneously formed between the mercury and thiol and deposited on the HMDE surface.
The surface precipitation process results in formation of a multilayer film on the electrode surface. The SW response of the investigated component mainly depends on the structure of the film
