Abstract: | The applactaion of atomic absorbtion spectrophotometry to determine lead, magnesium contents in calcium phosphate salts. The linear range of the lead content was 0.5- 5.0 μg/mL ( r = 0.99949) ; the average recovery was 99.0( RSD =0.5% ) ; The linear range of the magnesium content was 0.05 - 0.5 μg/mL(r =0.99549) ; the average recovery was 99.1 ( RSD =0.6% ). |
