【摘要】 用火焰原子吸收光谱法测定泛酸钙中的钙含量。以氯化钾溶液(0.1%,m/V)配制泛酸钙检测液,可消除空气-乙炔火焰的电离干扰作用。方法的线性范围为0.50~4.00μg/mL(r=0.999 2),加标平均回收率为98.7%,RSD为0.46%(n=9)。更多还原

【Abstract】 Calcium in calcium pantothenate were determined by flame atomic absorption spectrophotometry.Ionization interferences can be eliminated by the addition of 0.1% potassium chloride(m/V) to samples and standard(resolution).The calibration curve for calcium was linear over the range of 0.50~4.00 μg/mL.The average recovery was 98.7%,and RSD was 0.46%(n=9).更多还原
