Camsı Karbon Elektrotun Paladyum Katkılı İletken Poli(tiyonin) Filmi ile Modifiye Edilmesi

Camsı karbon elektrot iletken poli(tiyonin) destek malzemesi varlığında Pd tanecikleriyle modifiye edilmiştir. Tiyoninin polimerizasyonu elektrokimyasal yolla sulu tiyonin asetat çözeltisinde dönüşümlü voltametri kullanılarak gerçekleştirilmiştir. Pd kaynağı olarak K2PdCl4 kullanılmış ve Pd immobilizasyonu sabit potansiyelde elektroliz ile yürütülmüştür. Modifiye elektrotun karakterizasyonu elektrokimyasal olarak dönüşümlü voltametri ve elektrokimyasal empedans spektroskopisi yöntemleriyle gerçekleştirilmiştir. Elde edilen sonuçlar, modifikasyon işleminin elektrot malzemesinin iletkenlik özelliklerini önemli ölçüde arttırdığını göstermiştir.

Modification of Glassy Carbon Electrode with Palladium Doped Conducting Poly(thionine) Film

The glassy carbon electrode was modified with Pd particles using a conducting poly(thionine) as the support material. Polymerization of thionine was carried by electrochemical process from aqueous thionine acetate solution using cyclic voltammetry. K2PdCl4 was used as the Pd precursor and the Pd immobilization was performed with constant potential electrolysis. The modified electrode was characterized electrochemically using cyclic voltammetry and electrochemical impedance spectroscopy methods. The results revealed that the modification process significantly increases the conductivity properties of the electrode material.
