摘　　要：建立了固相萃取（SPE）气相色谱火焰光度（GC—FPD）检测方法，并且检测了地表水中8种有机磷农药，检测限在0．09～0．26ug／L之间，相对标准偏差为3．1％～9．7％（n=8），加标回收率达到61．3％～103．2％，与传统的气相色谱法相比，该方法具有比较高的重现性和选择性，在地表水有机磷农药的测定中具有很好的应用前景。A method for the determination of eight kinds of organophosphorus pesticides in surface water has been established by solidphase extraction（SPE） gas chromatography with flame photometric detector（GC - FPD）. The detection limits of this method for different organophosphorus pesticides were in the range of 0.09 - 0.26μg/L with relative standard deviations ranging from 3.1% to 9.7 % （ n = 8） and the recovery rates were from 61.3% to 103.2%. The method proposed by this paper possesses higher prodicibility and selectivity than traditional gas chromatography and is promising in real applications of determining the organophosphorous pesticides in surface water.
