为了消除黄金基体对部分被测(杂质)元素产生的干扰与抑制作用,采用基体匹配法,配制了含金基体混合多元素标准溶液.用ICP-AES法对该含金基体溶液中的Ag、Cu、Fe、Zn元素进行了均匀性检验.采用F和t检验法联用统计处理数据对该溶液进行了均匀性评价.检验结果表明瓶间和瓶内的均值和方差不存在显著性差异,证明该含金基体混合多元素标准溶液是均匀的.
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.
