| Abstract: | In this paper, a test of dissolving sample and the determinations of micros of Fe and Ca in high purity silicon is suggested. This method can avoid high background effect and overcome serious matrix interferences by the method of standard addition with satisfactory results. The precisions of Fe and Ca are 4.9 % and 5.5 %. The recoveries are betwecn 92 % and 102 %. |
| Keywords: | High purity silicon Micro iron calcium Method of standard addition Flame atomic absorption spectrometry |
