摘要
研究了用电感耦合等离子体发射光谱法结合归一法测定铬、镍合金中主体元素的分析方法。确定了仪器最佳测定条件,结果表明,主体元素铬、镍的加料回收率在99.3%~101.0%,RSD<0.45%,样品测定准确度和精密度好,能够满足产品分析的要求。
A combination of inductively coupled plasma emission spectrometry（ ICP-AES） normalization method was adopted to determine the main elements in chromium and nickel alloy. The optimum measuring conditions of the instrument were determined by experiments. Results showed that the recovery rate of chromium and nickel were between 99. 3 % ~ 101. 0 %,and the RSD 0. 45 %,which presents high accuracy and precision of determination. The method would meet the requirements of product analysis.
