Abstract
An analytical method for multiresidues of organochlorine and organophosphorus pesticides, including ethoprop (0-ethyl S, S-dipropylphosphorodithioate, prophos, Mocap), a nematocide, in crops was developed. The method consisted of extraction with a mixture of acetone and n-hexane, clean-up by florisil column chromatography and determination by gas chromatography (GC). The pesticides on the column were eluted with 200 ml each of 15% ether in n-hexane and ether. Ethoprop was eluted in the 2nd fraction and determined by FPD.
