Abstract: A differential pulse polarographic method for the determination of tetramethylthiuram disulphide (TMTD) by making use of its reaction with copper(I) perchlorate in acetonitrile has been developed. TMTD reacts with copper(I) perchlorate (1:1 molar ratio) and exhibits a well-defined, diffusion-controlled peak at - 120 mV showing five times more sensitivity than the one obtained due to TMTD alone. The linear relationship between concentration of TMTD and current intensity of peak at - 120 m V can be successfully adapted to the analysis of some fungicide and rubber accelerator formulations based on TMTD.
