摘要
探讨了用石墨炉原子吸收法测定无铅汽油中的铅。系统地研究了测定波长、测定浓度对测定方法的影响。提出了高浓度石墨炉原子吸收法测定无铅汽油中铅的方法。铅的检出限为 0 .0 0 5 mg/L,相对标准偏差 ( RSD,n=1 1 )在 1 .9%～2 .0 %之间 ,加标回收率在 95 .5 %～ 99.5
The determination of lead in nonlead gasoline by furnace absorption spectophotometry (FAS) is investigated in this paper The effect of determination wavelength and sample concentration on the method is systematically disscussed, and the determination method of lead in nonlead gasoline by high concentration FAS was produced The detection limit of lead is 0 005mg/L, and the relatively standard deviations (RSD,n=11) are 1 9%～2 0%, while the recoveries are 95 5%～99 5%
