    硝苯地平的分光光度测定

    Spectrophotometric Determination of Nifedipine

      摘要
    • 摘要: 采用分光光度法测定硝本地平的含量。测定波长为492nm。在1～20ug/ml范围内回归方程为A=0.025+0.028Cr==0.9990.平均回收率为99.76%(RSD=0.21%n=5)。方法简便、快速。

       

      Abstract: A new spectrophotometry method to determine nifedipine has been proposed. Thedetection wavelength is 492 nm. Beer's law is obeyed in the concentration range of 1-20 ug/ml.The regression equation is A = 0. 025+0. 028C, r = 0. 9990. The average recovery
