Abstract

The content of Pb and Cd in domestic ceramics was determined by flame atomic absorption spectrometry(AAS),and the optimum conditions for the determination were tested and discussed.The result showed that the limit of the method were 0.21 μg·mL-1(Pb) and 0.007 μg·mL-1(Cd),the reccvcling rate were 102.45% and 94.67%,RSDs were 2.10% and 3.14%.The method was sensitive,accurate,rapid and low actection limits,and suitable for trace Pb and Cd examination in laboratory.
