Determination of Al_2O_3,CaO,TFe_2O_3,MgO,MnO,SiO_2,TiO_2 in Limestone and Dolomite by ICP-AES

After limestone and dolomite samples were treated with K2CO3 and H3BO3,ICP-AES method was applied to the simultaneous determination of 7 components in limestone and dolomite.Parameters of instrument were optimized,and proper spectral lines were chosen to carry out the analysis.The experimental results were given out by a mean value model.The RSD was less than 0.60%.Compared with the standard values of the national first grade limestone and dolomite,the measurement results were the same.
