Preparation and Characterization of 4-hydroxybenzylidencarbamide-CTAB modified Glassy Carbon Electrode by using [Fe(CN)6] 4-/[Fe(CN)6] 3- redox system

4-hydroxybenzylidenecarbamide (ligand) has been synthesized by combination of 4-hydroxybenzaldehyde and urea. The ligand containing hydroxyl, imine and amide functional groups were characterized using IR, NMR spectroscopic techniques. The co-immobilization of cetyltrimethylammoniumbromide (CTAB) and ligand on glassy carbon electrode is achieved by drop coating technique. The ligandCTAB modified glassy carbon electrode is characterized by using ferro/ferricyanide redox system via electrochemical techniques such as cyclic voltammetry, chronoamperometry and chronocolumetry. Adsorption of these compounds onto glassy carbon electrode gives rise to stable redox probe for ferro/ferricyanide system. Active surface areas of bare GCE, CTAB/GCE, ligand/GCE and ligand-CTAB/GCE are calculated by using cyclic voltammetry and chronoamperometry techniques. The surface concentration of electroactive molecules on the different types of electrodes is calculated by using chronocoloumetry technique.
