N,Nʹ-bis(salisiliden)-2-aminobenzilaminonikel(II) Kompleksinin poli(pirol-ko-o-anisidin) kompozit filmlerinin yüzeyine immobilizasyonu ve NO2- iyonu tayini
Öz
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-LiClO4
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 NO2- iyonu için denenmiştir. Elektrokatalitik
çalışmalar 3:7 oranındaki modifiye kompozit filminin NO2-
iyonunun katalizlenmesinde oldukça yüksek bir aktiviteye sahip olduğunu
göstermiştir.

Immobilization of N,N'-bis(salicylidene)-2-aminobenzylaminonickel(II) complex on surfaces of poly(pyrrole-co-o-anisidine)/chitosan composite films and determination of NO2- ion
Öz
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 NO2- ion. The electrocatalytic studies
show that the modified composite film (3:7) is highly active for catalysis of
NO2- ion in pH=7 buffer solution.Electrocatalytic activities of
