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%).
