A rapid, simple, direct and sensitive method has been developed for th
e determination of thiram (tetramethylthiuram disulphide) based on the
formation of copper dimethyldithiocarbamate complex, which is rendere
d water-soluble by a cationic surfactant, cetytrimethylammonium bromid
e (CTAB). The method has been applied to the determination of thiram i
n synthetic mixtures, grain (wheat) samples and vegetables. (C) 1998 S
