| 摘 要： | 目的：测定乳酸钙片中乳酸钙的含量。方法：用水制备供试品溶液，加入氯化镧消除干扰，将供试品溶液喷入乙炔一空气火焰，用标准曲线法测定钙的含量。结果：钙元素在0～6.00μg/ml范围内，线性关系良好，相关系数r=0.9984；在标示量的80％、100％、120％三个浓度点测定回收率，平均回收率为99.6%，RSD为1.8％（n=9）。结论：本法简单、快速、准确、重现性好，适用于乳酸钙片中乳酸钙的含量测定。

| Abstract: | Objective：A flame atomic absorption spectrometry method for the determination of calcium lactate in Compound Calcium Lactate Tablets was established.Methods：The sample solutions were prepared with water and sodium chloride was added to eliminate ionization interference.Results：The sample solutions were injected into air-acetylene flame.The content of potassium were calculat-ed by standard calibration curves.The linear range fro potassium chloride was 0~6.00μg/ml,r=0.9984.The average recovery rate was 99.6%,RSD=1.8%（n=9）.Conclusion：The method is simple,rapid,accurate and reproductive. |
