摘要
用三氯甲烷萃取水中的四乙基铅,直接上石墨炉原子吸收仪进行测定。结果表明,方法相对标准偏差为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.
