摘要
采用氢氧化钠溶解样品,建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定ZL101铸铝合金中硅含量的分析方法。实验过程中优化了仪器的工作条件,选择硅测定最佳分析谱线。用含被测元素的标准样品绘制工作曲线,代替常用的内标工作曲线来校正方法,以消除共存元素和基体物质的影响。实验表明,硅测定的相关系数大于0.999,相对标准偏差为0.92%(n=10)。方法准确快速、精密度高,分析结果完全能够满足工业化生产控制要求。
Using sodium hydroxide to dissolve the sample,an analytical method for determining the silicon content of cast aluminium alloy ZL101 by inductively coupled plasma atomic emission spectrometry(ICP-AES)was established.During the experiment,the working conditions of the instrument were optimized,and the best analytical line for silicon determination was selected.In order to eliminate the influence of coexisting elements and matrix substances,the method was corrected by the standard sample containing the tested elements,which instead of the usual internal standard working curve.The experiment data indicates that the correlation coefficient of silicon determined is greater than 0.999,and the relative standard deviation is 0.92%(n=10)in this method.The method is accurate,fast and high precision,and completely satisfy the requirements of industrial production and control.
