Özet
In this paper, glassy carbon (GC) was modified through the electrochemical polymerization of chrysin (PolyChr/GC) on the surface in media where the electrode surface was aqueous and non-aqueous. Electrochemical polymerization was performed between +800 mV and +2600 mV in aqueous medium, and from +500 mV to +1800 mV in non-aqueous medium in 100 mV s(-1) sweep rate with 30 cycles. Modified electrode surface characterization was done by cyclic voltammetry and electrochemical impedance spectroscopy. In the study, the interaction between the PolyChr/GC electrode surface and Cu(II), Zn(II), Cd(II), Pb(II), Co(II) and Ni(II) ions was investigated by using the square wave voltammetry technique. The PolyChr/GC electrode surface was found to be sensitive and selective towards Cu(II), Pb(II) and Cd(II) ions.
