Electrochemical synthesis of the composite films wascarried out via cyclic voltammetry technique. They were characterized by FT-IR,cyclic voltammetry, SEM. The SEM results indicated that the particle size ofthe composite decreases with increasing o-anisidine ratio and the films becamemore likely to be smooth morphology. Also, electrochemical studies exhibitedthat the 3:7 composite film has good electrochemical stability. Immobilizationprocess of N,Nʹ-bis(salicylidene)-2-aminobenzylaminonickel(II) [NiL] complex onthe composite films was achieved in 0.15 M acetonitrile-LiClO4 via cyclicvoltammetry technique at 0.2-2.0 V potential range. The immobilization of theSchiff base metal complex, was determined by SEM migrographs. The SEM resultsclearly showed that the Schiff base metal complex was immobilized on thesurface of composite films. Also, after the immobilization process,electrochemical stabilitiy studies exhibited that modified electrodes not showany degradation. Electrocatalytic activities ofpoly(pyrrole-co-o-anisidine)/chitosan composite films immobilized metal complexexperimented for NO2- ion. The electrocatalytic studiesshow that the modified composite film (3:7) is highly active for catalysis ofNO2- ion in pH=7 buffer solution.Electrocatalytic activities ofpoly(pyrrole-co-o-anisidine)/chitosancomposite films immobilized metal complex experimented for NO2-ion.
