Abstract
Three spectrophotometric methods are described for the determination of carbaryl and propoxur in insecticidal formulations, water and grains, based on the formation of coloured species with p-aminophenol, p-N,N-dimethylphenylenediamine dihydrochloride and 1-amino-2-naphthol-4-sulphonic acid, respectively, under specified experimental conditions. All the methods are simple, sensitive and accurate to within ±1.0%.Keywords
