摘要:
采用一氯化碘的盐酸溶液吸收光谱法和三氯甲烷萃取〖CD2〗石墨炉原子吸收光谱法测定空气中四乙基铅,优化了试验条件。此方法对测定空气中四乙基铅的灵敏度、准确度都有很大的提高,方法的最低检出浓度为0.70μg/L,当采样体积为60L,四乙基铅最低检出浓度为0.0001mg/m3。对实际样品进行分析,四乙基铅的加标回收率为89.1%~105.9%。

Abstract:
Using a hydrochloric acid solution of iodine chloride absorption spectrometry and chloroform extraction — graphite furnace atomic absorption spectrometry determination of tetraethyl lead in the air, the test conditions were optimized. This method for the determination of tetraethyl lead in the air has greatly improved the sensitivity and accuracy. The method detection limit was 0.70μg/L. When the sample size is 60L, tetraethyl lead minimum detectable concentration was 0.0001mg/m3. By analysing of actual samples, tetraethyl lead recovery was 89.1%~105.9%.
