汽油样品预处理方法的探讨─汽油中痕量铅的测定
The Study of the Pretreatment Method for the Gasoline Samples The Determination of Lead in Gasoline
【摘要】 研究了测定汽油中痕量铅时两种预处理－ 测定方法： （１） 碘－ 正辛醇萃取－ 硝酸反萃取－ 离子交换、洗脱后用阳极溶出法测定； （２） 微波提取－ 原子吸收法测定。对两种方法的最佳条件进行了讨论。
【Abstract】 Two kinds of pretreatment method were studied for the determination of trace lead in gasoline:(1)The lead in gasoline was extracted by iodine-1-octanol,reverse-extracted by nitric acid,exchanged by ion exchanger,eluted by hydrochloric acid and determined by Anodic Stripping Voltammetry (ASV).(2)The lead in gasoline was extracted by nitric acid in a WR-1 microwave sample treatment system and then determined by atomic absorption spectrometery(AAS).Some conditions for both method (1) and (2) were optimized.
