| 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. |
