A new method for the determination of tetraethyllead (TEL) in water by SPME has been developed. TEL is extracted from the headspace over the sample and detected by GC-FID. The analytical procedure was optimized with respect to extraction temperature, stirring conditions, and extraction time. Linear calibration curves were obtained far TEL in range between 0. 08 μg/L and 10 μg/L. The detection limit obtained for TEL was found to be 0. 02 μg/L. The method was verified by spited water sample and the recovery rate was 96. 2%-98. 3% .%建立了水中四乙基铅的测定方法——顶空固相微萃取-气相色谱法,探计了影响水中四乙基铅萃取效率的温度、转速和萃取时间等因素.实验结果表明,在0.08 ~ 10 μg/L范围内线性关系良好,方法检出限为0.02 μg/L,实际水样加标回收率为96.2%~98.3%.
