Abstract
A method has been developed for determining carbaryl (l-naphthyl N-melhyl carbamate) in grains, based on hydrolysis of carbaryl with methanolic potassium hydroxide to 1-naphthol, reactlon with 4-aminophenazone in the presence of alkaline oxidizing agent, and spectrophoto-metric measurement at the absorption maximum at 475 nm. The relationship between absorbance and concentration ie linear in the range of 0.5-20 pg/mL. The method can be applied to levels as low as 0.3 ppm carbaryl in grains
