| Abstract: | A method for FAAS determination of Ca and Mg in industrial sodium phosphate tripolymer was proposed. The interferences of (PO4)3- are compensated by the addition of LaCl3 .The recoveries are 96.7% (for Mg ) and 104.2% (for Ca ) and the relative standard deviation are 1.45 % (for Ca) and 2.03% (for Mg ). The results are obtained by the standard addition method. The proposed method is proved to be rapid ,accurate and convenient. |
