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。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.
