Cyclic voltammetric adsorption behaviour of riboflavin at platinum electrode

Abstract

Cyclic voltammetric technique has been used to determine the electrochemical adsorption behaviour of riboflavin at platinum disc electrode in acidic solution. The electrode loses its activity after the first cyclic curve due to coating of its surface with the adsorbed species. The adsorption strength of riboflavin has been compared with some of the strongly adsorbed materials. This technique is employed to determine the amount of the species adsorbed on the surface of the electrode as the quantity of charge consumed is proportional to the area under the first cycle in the voltammogram.
