ABSTRACT:
A simple UV-spectrophotometric method for the determination of acephate(O,S-dimethyl acetylphosphoramidothioate) and profenofos(O-(4-bromo-2-chlorophenyl) O-ethyl S-propyl phosphorothioate) pesticides in buffer media is described. World over organophosphate pesticides contribute significantly in agricultural production and public health security. These compounds are used for pest control technology in crop production. Acephate and profenofos pesticides were determined in PH5.0 buffer medium using UV spectrophotometer. The absorption maxima was 255nm for acephate and 265nm in the case of profenofos pesticide. The linear range of detection was in the range of 7.0-42mg/land 3.0-18mg/l for profenofos,and acephate respectively.The correlation coefficients for acephate and profenofos were 0.9953and0.9992 respectively in PH5.0 buffer medium.
