摘　　要：本文研究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－原子吸收测定。对两种方法的最佳条件进行了讨论。In this paper, Two kinds of pretreatment method were studied for the derermination 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 Srripping Voltammerry(ASV). (2) The lead in gasoline was extracted by nitric arid in a WR-1 microwave sample trearment system and then determined by atomic Absorption spectrometery(AAS). Some conditions for both method(1) and (2) were optimized.
