Abstract

In this study, poly(pyrrole-co-o-anisidine)/chitosan composite films were electrochemically synthesized in various monomers feed ratio (pyrrole : o-anisidine; 7:3, 1:1 and 3:7) of pyrrole and o-anisidine on the platinum electrode. Electrochemical synthesis of the composite films was carried out via cyclic voltammetry technique. They were characterized by FT-IR, cyclic voltammetry, SEM. The SEM results indicated that the particle size of the composite decreases with increasing o-anisidine ratio and the films became more likely to be smooth morphology. Also, electrochemical studies exhibited that the 3:7 composite film has good electrochemical stability. Immobilization process of N,Nʹ-bis(salicylidene)-2-aminobenzylaminonickel(II) [NiL] complex on the composite films was achieved in 0.15 M acetonitrile-LiClO4 via cyclic voltammetry technique at 0.2-2.0 V potential range. The immobilization of the Schiff base metal complex, was determined by SEM migrographs. The SEM results clearly showed that the Schiff base metal complex was immobilized on the surface of composite films. Also, after the immobilization process, electrochemical stabilitiy studies exhibited that modified electrodes not show any degradation. Electrocatalytic activities of poly(pyrrole-co-o-anisidine)/chitosan composite films immobilized metal complex experimented for NO 2 - ion. The electrocatalytic studies show that the modified composite film (3:7) is highly active for catalysis of NO 2 - ion in pH=7 buffer solution. Electrocatalytic activities of poly(pyrrole-co- o -anisidine)/chitosan composite films immobilized metal complex experimented for NO 2 - ion. The electrocatalytic studies show that the modified composite film (3:7) is highly active for catalysis of NO 2 - ion in pH=7 buffer solution.

Özet

Bu çalışmada, poli(pirol-ko-o-anisidin)kitosan kompozit filmleri pirol ve o-anisidinin farklı monomer mol oranlarındaki çözeltilerinde (pirol : o-anisidin; 7:3, 1:1 ve 3:7) elektrokimyasal olarak sentezlendiler. Kompozit filmlerin sentezi dönüşümlü voltameri tekniği ile gerçekleştirildi. Kompozit filmleri FT-IR, dönüşümlü voltametri ve SEM teknikleri ile karakterize edildi. SEM analiz sonuçları o-anisidin oranı arttıkça kompozit filmlerin parçacık büyüklüklerinin giderek azaldığını ve oran daha da arttıkça düz bir yüzey halini aldığını göstermiştir. Ayrıca elektrokimyasal çalışmalar 3:7 oranındaki kompozit filminin elektrokimyasal olarak iyi bir kararlılığa sahip olduğunu ortaya koymuştur. N,Nʹ-bis(salisiliden)-2-aminobenzilaminonikel(II) [NiL] kompleksinin kompozit film yüzeylerine immobilizasyon işlemi 0.15 M asetonitril-LiClO 4 çözeltisinde 0.2-2.0 V potansiyel aralığında dönüşümlü voltametri tekniği ile gerçekleştirilmiştir. Schiff bazı metal kompleksinin kompozit filmlerinin yüzeyine immobilizasyonunun gerçekleştiği SEM görüntülerinden belirlenmiştir. SEM görüntüleri Schiff bazı metal kompleksinin kompozit film yüzeylerine immobilizasyonunun açık bir şekilde gerçekleştiğini göstermiştir. Metal kompleksi immobilizayonu gerçekleştirilmiş poli(pirol-ko-o-anisidin)/kitosan kompozit filmlerinin elektrokatalitik aktivite çalışmaları NO 2 - iyonu için denenmiştir. Elektrokatalitik çalışmalar 3:7 oranındaki modifiye kompozit filminin NO 2 - iyonunun katalizlenmesinde oldukça yüksek bir aktiviteye sahip olduğunu göstermiştir.
