Type: article
Abstract: A zeolitic imidazolate framework ZIF-67 was synthesized by an eco-friendly solvothermal method, using ethanol as solvent at room temperature. The morphology and structure of obtained ZIF-67 were characterized by X-ray diffraction, scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherm, energy dispersive spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR). The ZIF-67 modified graphite paste electrode (ZIF-67-GPE) was prepared and used for the electrochemical detection of acetaminophen (AC). Cyclic voltammetry (CV) and square wave voltammetry (SWV) were employed to investigate the electrochemical behavior of AC at ZIF-67-GPE modified electrode. At the optimal working conditions, the limit of detection was 0.2 μM (S/N = 3) in the linear range of 2 - 10 μM AC. The good analytical parameters indicated its applicability for AC determination in real samples.
