Abstract A new spectrophotometric method has been investigated for the determination of Carbofuran pesticide. The method was based on the hydrolysis of the pesticides. The hydrolyzed products, methylamine on reaction with sodium nitroprusside solution in acetone medium gives a purple colored solution. The absorbance of the resulting solution was measured at 530 nm. Conditions for the complete hydrolysis of pesticides and quantitative determination of methylamine were optimized. From the standard calibration plot of methylamine, the amount of pesticides was calculated. The amount of active ingredients in commercial products was determined from the amount of methylamine found. It was observed that lower concentration of the active ingredients were present in the commercial products. The limit of detection and quantification was calculated and found to be 0.804 and 2.68 ppm respectively. This article was published in Chemosphere and referenced in Chemical Sciences Journal
