Abstract

In this study, low cost, sensitive and selective chronoamperometric determination of vanillin (VNL) is firstly achievedby using a disposable poly(Eriochrome Black T) modified pencil graphite electrode (poly(EBT)/PGE). Electro-oxidationbehavior of 1.0 mM VNL was investigated at both poly(EBT)/PGE and PGE by the cyclic voltammetry (CV) method.CV measurements showed that oxidation current of VNL at poly (EBT)/PGE was much higher than the bare one.Furthermore, the pH effect on electro-oxidation current of VNL was tested at different pH values (2.0-8.0) of BrittonRobinson Buffer solution (BRBS) for poly(EBT)/PGE and the highest current was obtained at pH 7.0 BRBS.Significant analytical parameters such as linear response range (LRR), limit of detection (LOD), and sensitivity werefound as 0.050-10.0 µM, 0.013 µM and 5355 µA mM-1cm-2, respectively. The fabricated sensor was tested on a VNLcontaining sample (VNL content: 3.0%) and the result (3.04% ±0.01) obtained from the applicability study showed thatthe proposed sensor enables the determination of VNL with high accuracy and precision.

Özet

Bu çalışmada, vanilinin (VNL) düşük maliyetli, duyarlı ve seçici kronoamperometrik tayini tek kullanımlık bir poli(Eriokrom Siyahı T) modifiye kalem grafit elektrodun (poly(EBT)/PGE) kullanılması ile ilk defa gerçekleştirilmiştir. 1.0 mM VNL’nin elektro-yükseltgenme davranışı, hem PGE’de hem de poly(EBT)/PGE’de döngüsel voltammetri (CV) metodu ile incelenmiştir. CV ölçümleri poly(EBT)/PGE’deki yükseltgenme akımının yalın elektroda göre daha yüksek olduğunu göstermiştir. Ayrıca, poly(EBT)/PGE’de VNL’nin yükseltgenme akımına pH’nın etkisi, farklı pH değerlerindeki (2.0-8.0) Britton Robinson tampon çözeltilerinde (BRBS) test edilmiş ve en yüksek akımın pH 7.0 BRBS’de alındığı gözlenmiştir. Doğrusal yanıt aralığı (LRR), belirtme alt sınırı (LOD) ve duyarlılık gibi önemli analitiksel parametreler sırasıyla 0.050-10.0 µM, 0.013 µM ve 5355 µA mM-1 cm-2 olarak bulunmuştur. Tasarlanan sensör, VNL içeren bir örnekte (VNL içeriği %3.0) başarıyla test edilmiş ve uygulanabilirlik çalışmasından elde edilen sonuç (%3.04 ±0.01), önerilen sensörün, VNL’nin yüksek doğrulukta ve kesinlikte tayinine imkân sağladığını göstermiştir.
