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.
