DETERMINATION OF AMINOCARB IN WATER BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY

Aminocarb (4-dimethylamino-3-methylphenyl N-methylcarbamate) is a carbamate insecticide that has been used extensively in eastern Canada to control forest infestation by the spruce budworm. The direct analysis of carbamate insecticides by gas liquid chromatography (GLC) is deemed difficult because of on-column instability at normal operating temperatures. In view of the inherent difficulties with GLC analysis, high performance liquid chromatography (HPLC) is a promising alternative. This paper describes the analysis of aminocarb by reverse phase HPLC using ultraviolet absorbance in series with fluorescence detection. A pre-concentration technique using Amberlite XAD-4 resin for the analysis of rain water is also elaborated. Refs.
