Abstract: In order to eliminate the interference and inhibition effects of gold matrix on impurity elements, the gold matrix multi-element mixed standard solution was prepared using the matrix matching method. The homogeneity tests on Ag, Cu, Fe and Zn elements in the gold matrix multi-element mixed standard solution were performed by ICP-AES. And the homogeneity of the standard solution was evaluated by adopting the statistical data processing methods:F test andt test. The results showed that there were no significant differences in mean and variance, indicating that the gold matrix multi-element mixed standard solution was homogeneous.
