Resumen:
|
In the high-perfomance liquid chromatography determination of benomyl fungicide (methyl 1-(butyl carbamoyl)-2bensimidazolecarbamate) quantitative conversion to the metabolite methyl 2-bensimidazolecarbamate (MCB) is effected by the addition of 0.25 M hydrochloric acid during the rotary evaporation at 50-60C of the extraction solvents, methanol-ethyl acetate (1:9). This mild hydrolysis allows for the simultaneous determination of MBC and 2-amonibenzimidazole by cation-exchange chromatography in a varity of agricultural commodities, environmental samples, and worker exposure monitoring devices. The interferences usually occasioned by acid reflux hydrolysis are minimized. A Zipax SCX column, maintained at 60C, was used with a mobile phase of 0.025 M tetramethylammonium nitrate-0.025M niric acid
