| Abstract: | The content of Ca and Mg in potassium fluotantalate was determined by ICP-AES.After the conditions are determined of analytical spectral lines,detection limit,determination limit,bulk concentration and dissolving acidity,the Ca and Mg recovery of standard addition is 100.58%~102.50%,and RSD value is 0.74%~10.02% for the measured Ca and Mg content.The method is reliable,simple and fast to operate with high precision. |
