    倍增差示分光光度法测定复方甲硝唑溶液含量

    Determination of the Content of Compound Metronidazole Solution by Double Differential Spectrophotometry

      摘要
    • 摘要: 选择λ278nm 和λ300nm 作为甲硝唑和氯霉素二药的定量波长,通过两波长下吸光系数和配平倍数的测算,由工作曲线方程求得样品含量。实验测得甲硝唑和氯霉素的回收率分别为100.13%和99.73%,变异系数分别为0.3%和0.17%,说明方法可行。

       

      Abstract: In accordance with the principle of two wavelength coefficient double spectroph-otometry,the Double Differential Spectrophotometry was used for the determination of thecomponent,metronidazole and Chloramphenicolis,that is interferential each other.The det
