| Abstract: | The various factors that influence the determination result of soluble Pb,Cr in paint during the paint film preparation and pretreatment of samples were investigated and discussed in details.The result indicated that the film thickness,powder size,pH of HCl extraction solution and temperature showed dramatically influence on the result.It was recommended that these factors should be controled to improve the result consistency in different laboratory. |
