紫外分光光度法测定萘普生片的含量
UV spectrophotometric determination of Naproxen tablet
-
摘要: 采用乙醇为溶剂的紫外分光光度法测定萘普生片的含量,不受辅料干扰,简单、快速、准确。萘普生乙醇溶液的吸收系数(E331nm)为85.6,RSD为0.90%(n=20).平均回收率为100.4%,RSD为0.51%(n=5).本法与中和法作了比较,结果无明显差异(P>0.05).Abstract: A UV spectrophotometric method for the determination of Naproxen tablet was studied. The results showed that the method was simple,rapid and accurate and was not interfered by vehicle, The absorption coefficient (E1cm1%) of Naproxen in alcohlol was 85.6 and RSD was 0.90%(n=20).The average recovery was 100.4% and RSD was 0.51% (n=51). No significant difference was noticed between the results of this method and the volumetric method.
