Abstract
The present study proposed a facile and highly sensitive electrochemical sensor based on a carbon paste electrode modified by the metal-organic framework (MOF) [Cu(bpy)(H2O)2(BF4)2(bpy)] for the analysis of 2,4-dichlorophenol (2,4-DCP). X-ray diffraction (XRD) and Fourier transform infrared spectrometry (FT-IR) were used to investigate the morphology and composition, respectively, of [Cu(bpy)(H2O)2(BF4)2(bpy)]. Additionally, cyclic voltammetry (CV) was carried out to study the electrochemical performance. Considering the high charge transfer efficiency, strong adsorption capacity and large specific surface area of [Cu(bpy)(H2O)2(BF4)2(bpy)], our developed sensor was favorably selective to the detection of 2,4-DCP under optimum parameters, with a wide linear range of 4 to 100 μM and a low limit of detection (LOD) of 1.1 μM.
