ELECTROCATALYSIS OF BIOMOLECULES AT MODIF IED ELECTRODES .1. INVESTIGATION ON ELECTROCHEMICAL-BEHAVIOR OF NEW MEDIATOR CRESYL FAST VIOLET

The polarographic and voltammetric behaviours of cresyl fast violet we re investigated by various electroanalytical methods, e.g. sampled dir ect current polarography, pulse polarography, a.c. polarography and vo ltammetry and cyclic voltammetry. In the pH range 3 approximately 11 t he cresyl fast violet behaves as two electrons reversible redox proces s involving two protons. Reactant and product can strongly adsorb at e lectrode surface. Under certain conditions cresyl fast violet can form double-layer adsorption at mercury electrode surface.
