İletken Poli (Vinilferrosen) Filmi İçerisinde Prusya Mavisinin Elektrokimyasal Sentezi

Bu çalışmada, doğrudan doğruya demir içeren poli (vinilferrosen) (PVF) içerisinde prusya mavisi (PB) oluşturularak PB ve PVF ile modifiye edilmiş tek kullanımlık kalem grafit (KGE) elektrotun hazırlanması anlatılmıştır. Modifiye elektrotun PB ve PVF’in avantajlarını birleştirerek biyosensör çalışmalarında kullanılma potansiyeli bulunmaktadır. PB’nin polimerin içerisinde oluştuğu dönüşümlü voltametri ile gösterilmiştir. Dahası, deneysel çalışmalar modifiye KGE’un hidrojen peroksitin (H2O2) indirgenmesine karşı elektrokatalitik aktivite gösterdiğini ve bundan dolayı amperometrik bir H2O2 sensörünün geliştirilmesi için kullanılabileceğini ortaya koymuştur

Electrochemical Synthesis of Prussian Blue in Conducting Poly (Vinylferrocene) Film

In this study, preparation of prussion blue (PB) and poly(vinylferrocene) PVF modified disposable pencil graphite electrode (PGE) by formation of PB directly inside the iron-containing PVF is described. The modified electrode has the potential to be used for biosensor studies combining the advantages of PB and PVF mediators. Formation of PB inside the polymer has been confirmed by cyclic voltammetry. Furthermore, experimental studies showed that the modified PGE had electrocatalytic activity towards hydrogen peroxide (H2O2) reduction and thus can be used for fabrication of an amperometric H2O2 biosensor

Keywords:
