Özet

Bu çalışmada, Vanilin(VAN) tayini için modifiye elektrotlar hazırlanmıştır. Çok duvarlı karbon nanotüpler (MWCNT) asit muamelesi ile foksiyonalize edilmiş ve ardından altın nanoparçacıklar ardışık tekrarlanan taramalar ile altın nanoparçacık modifiye çok duvarlı karbon nanotüp camımsı karbon elektrokimyasal olarak biriktirilmiştir.

Abstract

In this study, modified electrodes were prepared for Vanilline (VAN) determination. Multiwalled carbon nanotubes (MWCNT) were functionalized with acid treatment and then gold nanoparticles were electrodeposited on the MWCNTs by applying several repetitive scans in order to form gold nanoparticles modified multiwalled carbon nanotube glassy carbon electrode (Au–MWCNT/GCE) surface. The morphology and structure of electrode surfaces were characterized by scanning electron microscopy (SEM). The resulting Au–MWCNT/GC electrode showed efficient behavior to VAN electro-oxidation. The calibration graph consisted of two linear segments of 7.0x10-86.5x10-6 mol L-1 and 7.0x10-6-7.5x10 mol L-1 with a detection limit of 3.8x10-8 mol L-1 thatobtained from differential pulse studies. The practical applicability of the proposed modified electrode was tested for the determination of VAN in commercial ice cream and milk powder. The satisfactory results show that the Au–MWCNT/GCE has promising potential in sensor applications
