ABSTRACT
In this study, a novel modified electrode was developed by incorporating furfurylamine keto‐oxime (FKO) as a functional compound for the sensitive electrochemical determination of Ni(II) ions. PPy and FKO–PPy modified electrodes were prepared using the cyclic voltammetry (CV) technique, while the determination of Ni(II) was carried out by differential pulse voltammetry employing PGE, PPy, and FKO–PPy electrodes. The experimental parameters influencing the electrode response, including the number of electropolymerization cycles, scan rate, and FKO concentration, were systematically optimized. Comparative DPV responses demonstrated that the FKO–PPy electrode exhibited the highest selectivity toward Ni(II) ions. A linear response was obtained in the Ni(II) concentration range of 2–10 ppm with a correlation coefficient of 0.9995, and the limit of detection was calculated as 0.378 ppm (S/N = 3). The applicability of the FKO–PPy electrode was further evaluated using deionized water, tap water, and wastewater samples, with the highest recovery values obtained in deionized water. In addition, interference studies indicated that the presence of common cations did not significantly affect the Ni(II) response of the FKO–PPy electrode.
