The application of polarography and related electroanalytical techniques to the determination of tetramethylthiuram disulphide

Abstract

Methods have been evaluated for the determination of tetramethylthiuram disulphide by d.c. and a.c. polarography. Linear calibration graphs were obtained over the concentration range 10^–4 to 10^–3 M by d.c. polarography, and 10^–6 to 10^–4 M by a.c. polarography. The electrode reaction was studied by cyclic voltammetry and evidence obtained to support the postulated mechanism of reduction of the S—S bond to give two dimethyldithiocarbamate molecules.
