dc.description.abstractElectrochemical modification of glassy carbon (GC) electrode by naringenin (NG), a flavonoid derivative, and applicability of electrode modified in this way for determination of copper(II) (Cu(II)) ions is reported in this study. Surface modification experiments were performed in phosphate buffer solution (PBS), pH 7, in the 0.0 mV and +1400 mV potential ranges with a sweep rate of 100 mV s(-1) and 30 cycles. The surface modification of GC electrode was performed with NG using cyclic voltammetry (CV), whereas the characterization of this sensor electrode was performed using CV and electrochemical impedance spectroscopy (EIS). The sensitivity of GC electrode modified in described way towards Cu(II) ions was investigated in Britton-Robinson (BR) buffer solution, pH 5, by differential pulse voltammetry (DPV). For the calibration curve, a series of standard Cu(II) solution from 1.0 x 10(-12) M to 1.0 x 10(-6) M was prepared. The NG modified GC (NG/GC) sensor electrode, has a good repeatability, was applied for Cu(II) ions determination in Beysehir lake (in Konya, Turkey) water sample. Detection limit was obtained as lower as 1.0 x 10(-12) M. The proposed method was simple, rapid, low cost and sensitive for the determination of Cu(II) ions.en_US
