摘　　要：以电感耦合等离子体光谱法(ICP--AES)直接同时进行硅铁中Mn、Al、Ca、Cr、Ni、Cu等元素的测定,对试样溶解方法、元素干扰情况、元素分析谱线等进行了试验。该方法操作简便、快速,检出限除钙外都低于0.005%,且RSD小于1%。The direct simultaneous determination of Mn, AI, Ca, Cr, Ni and Cu in ferrosihcon with ICP- AES method is reported. The optimal testing parameters, methods for sample solution, interference of elements were determined after optimizing operation procedures of instrument. The results proves that this method is precise, quick and easy to be operated. The preciseness, recovery and checking with standard sample are satisfied.
