提出了中空纤维膜萃取-气相色谱法测定水中有机氯农药的方法。首先研究了8种有机氯农药的线性范围，然后测定了中空纤维膜萃取对水中有机氯农药的回收率，最后用中空纤维膜萃取-气相色谱法对实际水样进行检测。结果表明，8种有机氯农药在0.5~10μg/L范围内具有良好的线性关系，中空纤维膜萃取法对水中8种有机氯农药的富集倍数为389~464，回收率为77％~92％，可以满足分析要求。%A method of determination of organo-chlorine pesticide in their aqueous by hollow fiber membrane extraction-gas phase chromatography was put forward. Firstly, linear ranges of eight organo-chlorine pesticides were investigated. And then the recovery of organo-chlorine pesticide in their aqueous by hollow fiber membrane extraction was measured. At last, the real water samples were detected by method of hollow fiber membrane extraction-gas phase chromatography. The results showed, eight organo-chlorine pesticides have good linear ranges between 0. 5 μg/L and 10 μg/L. Enrichment times and recovery rate of eight organo-chlorine pesticides reached 389-464, 77%-92%, respectively. This method can meet the demand of analysis of real water sample.
