Abstract
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.
