采用液液微萃取与气相色缈质谱法联用技术建立了测定水样中四乙基铅的方法。同时还对萃取溶剂进行选择，结果表明：选择了二氯甲烷作为萃取溶剂，氯化钠加入量10g，该方法检出限为0．03μg／L，线性范围为0．20-10．Oμg／L，线性相关系数为0．9999，测定饮用水源水和地表水中的四乙基铅，加标回收率为89．5％～101．7％，相对标准偏差为3．7％-5．9％。%A method for the determination of tetraethyl lead in water by liquid - liquid extraction coupled with gas chromatography/mass spectrometry (GC/MS) was established. Extraction solvent was optimized,The result showed that,CH2Cl2 was selected as extraction solvent, the amount of sodium chloride added was 10g. Under the optimum conditions,the limit of detection was 0. 03 μg /L , the calibration graph was linear in the range of 0.20 - 10.0μg/L, with the correlation coefficients of 0. 9999. The recoveries of the method were 89.5% - 101.7%, and the relative standard deviations ranged from 3.7% -5.9% .
