| Abstract: | A method for the determination of calcium and iron in industrial silicon by flame atomic absorption spectrumetry has been described in this paper. The method of sample preparation and the interference elements have studied. Under experimental conditions,the detection limitations of these elements are respectively 0. 005%for Ca, 0. 003%for Fe. The relative standard deviation is less than 10%. This method is simple and quick with high accuracy and precision. The results achieued are very satisfactory. |
