Voltammetric evidences for the interaction of riboflavin with cadmium in aqueous media
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) p...

| description | 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. |
