摘　　要：用火焰原子吸收分光光度法测定了汽车尾气中铅的含量,该方法的检出限为0.015mg/Nm3,线性方程A=0.0126C+0.005,相关系数r=0.9999,回收率为96%～99%.该法简便,快速,灵敏,适合于汽车尾气中Pb的测定.A method for determination of Pb from automobile exhaust by FAAS4 is reported in this paper. The detection limit is 0.015 mg/Nm3; equation of linear : A= 0.012 6C+ 0.05, ? =0.999 9; recovery of the method is from 96% to 99% . The method is fast, convenient, sensitive and suitable for determination of Pb from automobile exhaust.
