摘要：

Dithiocarbamate fungicides react with luminol to produce an intense chemiluminescence in the presence of hexacyanoferrate(III) and hexacyanoferrate(II) in alkaline solution. Based on this fact, a simple and sensitive method for the determination of dithiocarbamate fungicides by reversed-phase ion-pair liquid chromatography with chemiluminescence was developed. The mancozeb and propineb of dithiocarbamate fungicides were able to be separated using 5 mM phosphate buffer (pH 7.5) contained 2.5 mM tetrabutylammonium hydrogen sulfate/methanol (75:25) in a short time. The proposed method could be applied to the analysis of vegetables spiked with dithiocarbamate fungicides.
