摘要
采用电感耦合等离子体原子发射光谱法（ICP—AES）测定中碳铬铁中硅锰磷的含量。试样经湿法处理后，通过一系列实验，选择仪器合适的工作条件进行测定，方法的回收率在96％～103％之间，相对标准偏差均小于3％。与传统方法相比，ICP—AES法快速、准确、精密度高。
The content of silicon, manganese and phosphorus in medium -carbon chromium iron is deter- mined with ICP - AES method ： at first sample is wet treated, and then conditions selected for the instrument through a series of experiments. The recovery rate of this method is between 96 to 103 percent, all relative standard deviations smaller than 3 percent. Compared with the traditional method, this method is fast, accu- rate and has high precision level.
