摘要
采用三氯甲烷萃取-石墨炉原子吸收光谱法测定水中四乙基铅,优化了试验条件。方法在2.00μg/L^50.0μg/L范围内线性良好,检出限为1.3×10-5mg/L,标准溶液测定的RSD≤8.6%,实际水样加标回收率为90.4%~108%。
The tetraethyl lead in the water was determined by extraction of trichloromethane/graphite furnace atomic absorption spectrometry.The optimized tests produced the following results： a good linearity in range from 2.00 μg/L to 50.0 μg/L,detection limit 1.3×10-5 mg/L,RSD of standard solution ≤8.6%;spiked recoveries of practical samples 90.4%～108%.
