摘要
本文研究了试样经硝酸和硫酸或氯酸钾和盐酸分解,用ICP发射光谱法测定矿石中砷的方法。通过实验选择了仪器最佳工作条件和分析线对,从各种不同基体成分回收试验结果得出回收率为92%以上。本方法的相对标准偏差在2%~4%之间,结果比较满意。
A method for determinate As in ore were studied by inductively coupled plasma - atomic emission spectrometry, The samples were decomposited by HNO3 and H2SO4 or potassium chlorate and HC1. Optimum working conditions of instrument and the analytical lines were selected by test. Over 92 96 recovery was got according to recovery test result from all kind of differ fundamental. RSDS were in the range of 2 % -4 %. Results are satisfaction.
