Abstract:A method for the determination of Mn, Cu, Ni, Cr, V, Mg, Zn, Ti, Fe, Al, Ca in industrial silicon was proposed. The analytical lines of determined elements, the operation parameters by ICP-AES, the dissolution of samples, the effects of inorganic acid, the influence of coexisting elements were studied in detail. The experiment results indicate that the methods has the advantages of high sensitivity and simultaneous determination and convenience. The relative standard deviations of the method were 1.86% - 8.12% , and recoveries were 85% - 106%.
Keywords:ICP-AES  Industrial silicon  All elements
