摘要：

A rapid fluorimetric method is reported for the determination of thiamine based upon its interaction with Co(II) ion in the presence of base and a nonionic Triton X-100 micellar medium.The effect of different experimental variables upon the fluorescence intensity were assessed. The detection limit for thiamine is 5.0 x 10(-8)M(lambda(ex)=375nm, lambda(em)=433nm). The method was successfully applied for determination on thiamine in variety of samples with good accuracy being achieved.
