Electrografting and Surface Properties of Some Substituted Nitrophenols on Glassy Carbon Electrode and Simultaneous Pb2+ - Cd2+ Analysis via Assist of Graphene Oxide Terminated Surface

Ali Osman SOLAK

A new electrode was prepared by the electrooxidation of orto-, meta-, and para-substituted nitro phenols on glassy carbon electrode. Electrochemical modification of the electrodes was carried out in 0.01 M HCl using cyclic voltammetry (CV). Then nitro groups in the covalently grafted nitro phenol derivatives on GC electrode were reduced to amine groups in 0.01 M HCl. The electrochemical behavior of the modified electrodes was studied in the presence of electroactive redox probes such as ferrocene and ferricyanide by CV and electrochemical impedance spectroscopy (EIS). X-ray photoelectron spect ...Daha fazlası
