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=0．9992），加标平均回收率为98．7％，RSD为0．46％（n=9）。
Abstract：Calcium in calcium pantothenate were determined by flame atomic absorption spectrophotometry. Ionization interferences carl 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）.
