Abstract

PAAQ (Poly(2-amino-anthraquinone)) films were prepared through electrochemical oxidation of 2-amino-anthraquinone monomer in anhydrous acetonitrile using the supporting electrolyte tetrabutylammonium perchlorate. The effects of scan rate, cycle number, and monomer concentration on polymer film formation were investigated. Electrochemical detection of nitrobenzene (NB) on PAAQ modified glassy carbon electrode was examined with voltammetry and differential pulse voltammetry. The polymer-modified electrode exhibited excellent reducing ability towards NB compared to the unmodified electrode. The NB sensor developed on the polymer-modified electrode showed a wide linear response range of 0.0625 - 8 mM and a low detection limit of 2.294 mM.

Özet

PAAQ (Poli(2-amino-antrakinon)) filmler, destekleyici elektrolit tetrabütilamonyum perklorat kullanılarak susuz asetonitril içinde 2-aminoantrakinon monomerinin elektrokimyasal oksidasyonu ile hazırlandı. Polimer film oluşumu üzerinde, tarama hızının, çevrim sayısının ve monomer konsantrasyonunun etkisi incelenmiştir. PAAQ ile modifiye edilmiş camsı karbon elektrot üzerinde, nitrobenzenin (NB) elektrokimyasal tespiti dönüşümlü voltametri ve diferansiyel puls voltametri ile incelendi. Polimer modifiye elektrot, modifiye edilmemiş elektrot ile karşılaştırıldığında NB'ye karşı mükemmel indirgeme yeteneği sergiledi. Polimer modifiye elektrotta geliştirilen NB sensörü, 0.0625 - 8 mM arasında geniş bir doğrusal cevap ve 2.294 mM düşük dedeksiyon limiti gösterdi.
