摘要
探讨了用异丙醇做溶剂,用火焰原子吸收法测定汽油中铅的方法,实验证明,此方法的回收率在95.5%～104%之间,变异系数在1.38%～2.55%之间,此方法省时,准确,降低实验成本,简化实验步骤,减少实验室污染。
The lead of gasoline is dissolved by isopropanol and analyzed by flame atomic absorption spectrophotometer.The recovery rate of the known sample is 95.5%～104% while the variable coefficient of this method is among 1.38%～2.55%.It is proved that the analytical speed has been quickened and the operation has been simplified.
