Abstract

A method for the determination of diethyllead in urine by flameless atomic absorption spectrometry after chelation with glyoxal-bis (2-hydroxyanil) and extraction of the formed complex with methyl isobutyl ketone is described. The method is specific in relation to both triethyllead and inorganic lead. The limit of detection was 3.2 micrograms Pb/l and the relative standard deviation in the concentration range 20-100 micrograms Pb/l was 0.076.

摘要

本文描述了一种通过无火焰原子吸收光谱法测定尿液中二乙基铅的方法。该方法是先将二乙基铅与乙二醛双(2-羟基苯胺)螯合,然后用甲基异丁基酮萃取形成的络合物。该方法对三乙基铅和无机铅均具有特异性。检测限为3.2微克铅/升,在20 - 100微克铅/升的浓度范围内,相对标准偏差为0.076。
