国家标准ＧＢ Ｔ 80 2 0 - 87《汽油铅含量测定 (原子吸收光谱法 )》 ,是将汽油试样用甲基异丁基甲酮稀释 ,加入磺和季铵盐与烷基铅化合物反应使之稳定。以氯化铅为标样 ,用火焰原子吸收光谱法测定试样中铅含量。采用上述处理方法 ,虽然稳定性高 ,重现性好 ,但灵敏度低 ,成本高 National standard GB T 80 2 0-87 “Determination of lead content in gasoline (atomic absorption spectrometry)”, is the gasoline sample diluted with methyl isobutyl ketone, adding sulfonic acid and quaternary ammonium salt with the alkyl lead compound to stabilize . With lead chloride as the standard sample, the content of lead in the sample was determined by flame atomic absorption spectrometry. Using the above treatment, although the stability, reproducibility, but low sensitivity, high cost
