【摘要】 直接用白铜合金片样定性扫描测定Ni、Cu和Zn的X-射线荧光强度值,作强度归一化可以半定量确定主量元素质量百分数(％),结果发现元素之间有明显的吸收—增强效应。改用溶液滤纸片薄膜制样测定,强度归一化的计算值与试样元素的推荐值十分吻合,说明元素之间的吸收—增强效应基本消除,研究的方法精确度高。更多还原

【Abstract】 By using white copper alloy tablet to determine Ni - Cu- Zn X - ray fluorescence instensity qualitively, and doing intensitive normalization may semi - quantitatively analyse major components percent, the results have shown that there is obvious absorption and enhancement effect. Instead of filter paper thin film technique, the result of instensitive normalization coincides with the recommendation of sample element, this means that the interelement absorption and enhancement effect have been essentially eliminated, and the accuracy is satisfied.更多还原
