چکیده
The present study developed a facile and fast electrochemical approach to sensitively analyze Sudan I using Fe3O4-ZIF-67 nanocomposite plus ionic liquid (IL). carbon paste electrode (CPE) modified with Fe3O4-ZIF-67/IL exhibited an excellent sensing performance I. Compared the unmodified CPE, Fe3O4-ZIF-67/ILCPE could significantly increase peak current of oxidation decrease overpotentials. Under best experimental conditions, sensor differential pulse voltammetry (DPV) technique responded linearly (0.5 - 560 μM) low limit detection (LOD) 0.1 μM. Additionally, applicability effectiveness our proposed method in food samples was confirmed by acceptable recovery rate (96.0 103.6 %).
