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 ligand-
CTAB 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.
