Modification of glassy carbon electrode by the electrochemical oxidation of 3-aminophenylcalix[4]pyrrole in nonaqueous media

Ali Osman SOLAK

3-Aminophenylcalix[4]pyrrole (3APCP) was grafted to a glassy carbon (GC) surface during the electrochemical oxidation process in 0.1 M tetrabutylammoniumtetra-fluoroborate (TBATFB) containing acetonitrile solution. The presence of a surface film was confirmed electrochemically by comparing voltammograms of dopamine and ferricyanide redox probes at the bare and modified electrodes. Reflection-absorption infrared spectroscopy (RAIRS), XPS, atomic force microscopy (AFM), ellipsometry and the contact angle measurements were also employed to characterize 3APCP film on GC electrode. RAIRS analysis r ...More

High energetic body source and strong antioxidant quercetin, morin and rutin: Their covalent grafting onto the glassy carbon electrode surfaces and investigation of surface properties

Ali Osman SOLAK

Herein, electrochemical oxidation and grafting of quercetin, morin and rutin as important biological molecules has been studied with the cyclic voltammetry technique by using a glassy carbon electrode. Electrochemical studies have been performed potentiostatically within a one-compartment three-electrode cell at room temperature. Glassy carbon electrode was used as a working electrode and Pt was used as a wire counter electrode. Ag/Ag+ (10 mM AgNO3), non-aqueous reference electrode calibrated to the E1/2 of ferrocene redox probe and Ag/AgCl/KCl (sat.), an aqueous reference electrode calibrated ...More
