摘要
利用吹扫捕集-气相色谱/质谱联用法对地表水中四乙基铅进行了实验分析,结果表明:该方法在0.1μg/L~10μg/L范围内线性良好,方法检出限为0.02μg/L,实际样品空白加标回收率范围为75%~91%,相对标准偏差为6.8%。
A purge and tarp method with gas chromatography and Mass spectrometry(GC/MS) was developed for the determination of tetraethyl lead(TEL) in surface water. The method shows good linearity from 0.1 ug/L to 10 ug/L; the limits detection was 0.02 ug/L. The blank recoveries ranged from 73% to 89%, and the relative standard deviations was 6.6%.
