Abstract: The content of lead and copper in 9 kinds of common coatings formula were measured by the method of graphite furnace atomic absorption spectrometry. And the related properties of coatings and their cured films were tested. The results showed that the correlation coefficient of lead and copper content was 0. 998 1 and 0. 996 6 respectively in a particular instrument working conditions and the linear range. The heavy metal content (i. e., lead and copper)in the measured samples, and the fineness, hiding power, hardness and adhesion of the film are qualified to the national standard.
