| 摘 要： | 应用溶剂萃取，利用紫外分光光度法直接测定了AD钙营养盐中维生素D的含量。实验结果表明：维生素D不溶于水，易溶于乙醇中，在无水乙醇中较为稳定，在乙醇溶液中的特征吸收峰为λmax265nm。标准曲线的线性关系好，r=0．9996，实验添加回收率为98．04％。

| Abstract: | At present, Content measurement of vitamin D in AD calcium nutritive salt does not appear in papers. The application solvent extraction has been studied in this text,the directly to ascertain by measuring the content of vitamin D in AD calcium nutritive salt with UV-spectrophotometry. This method is accurate and reliable ,simple and convenient easy to operating. the sensitivity and the linear relation( R=0.9996 )of the method is good, the average rate of recovery is 98.04%. |
