制备了单相汽油-乙醇-水混合物，用于用水性标准物进行标准化和消除汽油移液困难。采用标准加入校正法，用火焰原子吸收光谱法测定汽油中的铜、铅、钴。将该方法与微波炉硝酸消解汽油的分析结果进行了比较，结果一致。在原汽油样品中，检出限为1.5 μg kg−1Co、2.5 μg kg−1Cu和4.0 μg kg− 1 Pb。
Single phase gasoline–ethanol–water mixture was prepared for performing standardization with aqueous standards and for the elimination of difficulties with pipetting of gasoline. Standard addition calibration method was applied to the determination of Cu, Pb and Co in gasoline by electrothermal atomic absorption spectrometry. Good agreements were found for the analysis results of the present “direct” method compared with those obtained by digesting gasoline in microwave furnace with nitric acid. The limit of detection values were 1.5 μg kg−1Co, 2.5 μg kg−1Cu and 4.0 μg kg−1Pb in original gasoline samples.
