摘要
应用化学计量学-X-射线光谱分析软件包CMXRS V2.1,在基本参数法进行基体效应校正的基础上,选择合适的样条函数,并采用微孔面罩及石蜡衬底等实验技术,测定了29个黄金标准样品中的Au、Ag、Cu和Zn。结果证明,方法可行。Au含量在99%以上的样品,Au的分析误差不超过0.14%,Au含量小于99%的样品,Au的分析误差不超过0.25%。
X-ray fluorescence analysis was used to analyze 29 gold reference materials for the elements of Au, Ag, Cu and Zn, in which the chemometric-X-ray spectrometry software package (CMXRS) V2. 1 was applied. Fundamental parameters method was used to correct matrix effect, combined with careful choice of spline function and the use of micro-hole cover and wax-base. The analytical error for > 99% and < 99% gold samples was ≤0. 14% and <0. 25%, respectively.
