【 摘 要 】

Evidence for the interaction of riboflavin with cadmium (Cd) in aqueous media was studied by cyclic voltammetry, differential pulse anodic stripping voltammetry and chronocoulometry. It was found that Cd exhibits a 1:1 complex with riboflavin in aqueous KCl solution to bind between O(24) and N(12) positions of riboflavin depicted from the semi-empirical computation. The overall stability constant (logβ = 9.95) of the complex obtained from differential pulse anodic stripping voltammetric data is a good agreement for the formation of a very stable Cd–riboflavin complex in aqueous media.
