摘　　要：用三氯甲烷萃取水中的四乙基铅,直接在石墨炉原子吸收仪上进行测定。结果表明:本方法的相对标准偏差为5.9%,平均回收率在90.4%～108%之间,检出限为1.3×10-5mg/L,准确度高,精密度好。The tetraethyl lead was extracted from water with Trichloromethane. The extract was detected by Graphite Furnace Atomic Absorption Spectromettry method. The detection limit was 1.3 × 10 -5 mg/L. The average recoveries were between 90. 4% - 108%. The method is effective, fast and accurate.
