摘要：

A rapid, sensitive method is described for the determination of ethylenethiourea (imidazolidine-2-thione) in ethylenebisdithiocarbamate fungicides. High-performance liquid chromatography is used with an ultraviolet spectrophotometric detector. The results are compared with those obtained using gas-liquid chromatography. All fungicide samples assayed contained ethylenethiourea, and gas-liquid chromatography indicated higher concentrations than high-performance liquid chromatography. Keywords: Ethylenethiourea determination; ethylenebisdithiocarbamate fungi-cides; high-performance liquid chromatography; gas-liquid chromatography.
