摘    要:研究了弱碱性介质中,硝基安定经H2O2和紫外光共同作用后,反应产物的荧光特性(λex=355nm,λem=465nm),提出了一种测定硝基安定的新方法.标准曲线的浓度范围为0.25~3.00mgL-1.方法的相对标准偏差和检测限分别为2.3%和0.13mgL-1.可直接用于片剂中硝基安定含量的测定.

关 键 词:硝基安定,荧光分析法

Abstract:Based on a great fluorescence Stokes shift of sulfosalicylic acid, which has been observed in the experiment, a mechanism of intramolecular proton transfer of sulfosalicylic acid has been described. A rapid fluorimetry for the determination of sulfosalicylic acid in acidic tin electrolating solution has been established. With this method, only 5 to 10 minutes were needed for one time of determination, and the determination was not interfered by the coexisting components in the electroplating solution. The relative standard deviation was less than 3%.
Keywords:Sulfosalicylic acid  Intramolecular proton transfer  Rapid fluorimetry
