Fund Project: The project was supported by the National Natural Science Foundation of China.

The electrochemical reaction mechanism of Vitamin B₂ on platinum electrode in acid aqueous solution has been studied by thin layer cyclic voltammetry (TLCV) and thin layer spectroelectrochemistry (TLSEC). The results indicate that there is a redox process of VB₂ via a semiquinone radical to dihydroflavin. The radical intermediate has been detected by in-situ UVSEC method for the first time.
