Abstract:ICP-AES is a method that tests the CaO and MgO content in bauxite and kaolin, based on the acidification of hydrochloric acid 'after alkali fusion. The detection limit of this method is CaO: 0.002 2%, MgO: 0.000 4%. After the continuous tests for twelve times on national standard substance GBW03122, this precision of method is (RSD) CaO: 0.67% and MgO: 1.50% respectively, which are coordinate with standard indexes.
Keywords:ICP-AES bauxite kaolin CaO  MgO
