| Abstract: | This paper described the method that a certain amount of Sr is put into the standard solution to eliminate ion interference and atomic absorption spectrophotometry is used to quickly determine the contents of CaO,MgO and MnO.Its RSD is below 2%(n =6),tested by the national standard material and the result is in conformity with standard value.The method proves to be accurate,simple,convenient,fast and quite practicable. |
