GNP-COPPER HEXACYANOFERRATE MODIFIED ELECTRODE FOR VOLTAMMETRIC CHARACTERIZATION AND BEHAVIOR IN THE PRESENCE OF BUTYLATED HYDROXYANISOLE

The modification of a graphite electrode with copper hexacyanoferrate as mediator is discussed how to determine Butylated Hydroxyanisole (BHA). Copper hexacyanoferrate modified electrode was equipped by dipping of metal solution on a GNP-L-Cys-wax (gold nano particle- L-cysteine) composite graphite electrode. The chemically modified electrode's electrochemical behavior was assessed by FESEM, UV and electrochemical studies etc. The cyclic voltammogram obtained by applying the potential flanked by 200 mv and 900mv using 0.1 M KNO3 solution showed a pair of redox peaks. BHA exists to undergo electrocatalytic oxidation at the working electrode. The feat of the working electrode in static and dynamic conditions to be appraised. The rectilinear current retort of the working electrode under both conditions for the determination of BHA confirms its utility as an amperometric sensor for batch and flow systems. The working electrode preserve is simply erect by a simple immobilization method and has the advantages of good dependableness, hasty retort and astonishing firmness. The use of the modified electrode as an amperometric sensor for determining BHA in commercial samples has been proposed
