چکیده
|
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 (log. β = 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. © 2012 production and hosting by elsevier b.v.
