Electrochemical Grafting by Reduction of 4-Methylaminobenzenediazonium Salt at GC, Au and Pt Electrode: Investigation of Sensitivity Against Phenol by Cyclic Voltammetry

The aim of this study is to modify a glassy cabon, gold and platinum electrodewith 4-methylaminobenzenediazonium salt (mabdas) to evaluate the possible applicationon the detection of phenol by cyclic voltammetry (cv). diazonium salt was reducedelectrochemically and covalently electro-grafted onto gc, au and pt electrodes surface toform modified electrodes in non-aqueous media. the electrode surfaces were modified withmabdas in acetonitrile (ch3cn). mab modified gc (mab/gc) electrode was used forthe phenol determination in aqueous media. the effect of ph on the electrochemical behaviorof the modified gc electrode was investigated for the phenol detection.
