摘要：

Synchronous fluorescence possibilities for the determination of three water-soluble vitamins, thiamine, pyridoxine and riboflavin, in presence of bis-2-ethylhexysulfosuccinate sodium salt (AOT) micelles, were studied. Synchronous fluorescence was chosen due to the good analytical characteristics found. Repeatability, expressed as %R.S.D. was smaller than 1.4, sensitivity calculated as the slope of the straight line was of the order of 10(10) l mol(-1) cm(-1) in all the cases and detection limits were 12 mug l(-1) for thiamine, 10 mug l(-1) for pyridoxine and 9 mug l(-1) for riboflavin. Synchronous fluorescence was applied to carry out the analysis of the three vitamins in pharmaceuticals. (C) 2001 Elsevier Science B.V. All rights reserved.
