(a) The stability of the PANI-ZnO/GCE by differential pulse voltammogram peak “a” first-day modification of the electrode and peak “b” after ten weeks using the same electrode. Interference study of 0.1 M of PBS (pH = 7.0) containing 1.0 × 10⁻⁸ M PC and using PANI-ZnO/GCE at a scan rate of 50 mV/s for 1.0 × 10⁻⁸ M (b) of uric acid, and (c) Na⁺ and K⁺ ion.
