Abstract

This paper presents the developed techniques and optimized conditions for the amperometric determination of gold with a solution of pheniccarboxymethyldiphenylthiocarbazone. The nature of the limiting anode currents and the number of electron donations during oxidation of one depolarizer molecules and optimized conditions for the determination of Au(III) solution of pheniccarboxy methyldiphenylthiocarbazone. On the basis of the obtained data, the possibility of applying the developed electrochemical methods to the analysis of real natural objects and industrial materials is shown. In all cases, the results obtained are processed by techniques and procedures known in the literature and are evaluated metrologically
