摘    要:应用原子吸收分光光度法测定磷酸钙盐中铅、镁的含量。铅含量的线性范围为0.5~5.0μg/mL(r=0.99949),平均回收率为99.0(RSD=0.5%);镁含量的线性范围为0.05~0.5μg/mL(r=0.99549),平均回收率为99.1(RSD=0.6%)。

关 键 词:原子吸收分光光度法  磷酸钙盐

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% ).
Keywords:atomic absorption spectrophotometry  calcium phosphate salt  lead  magnesium
