The rapid method was investigated for the determination of organophosphorous pesticides: parathion, methylparathion, methyldemetone, EPN: in waste waters. Equal volumes of sample water and acetone were mixed by the ultrasonic irradiation for 5 min and centrifuged on (3000〜4000) r.p.m. for 5 min. Pesticides in 1 *l of the water acetone mixture phase were determined by a gas chromatograph with a 2 % silicon DC QF-1 column(3mm i.d. × 2m) at 210 ℃ and a flame thermionic detector (FTD). The selectivity of organophosphorous compounds against hydrocarbons was improved by FTD without collector voltage. The detection limit of organophosphorous pesticides was 0.1mg/l. The recoveries of 1.0mg/l pesticides in waste waters containing 100 mg/l soybean oil were (99〜106) % and coefficients of variation were (2.7〜8.7) %. The whole procedure was completed within 20 min.
