عنوان انگلیسی Highly Electrocatalytic Oxidation of Bisphenol A at Glassy Carbon Electrode Modified with Metal-organic Framework MOF-508a and its Application in Real Sample Analysis
چکیده انگلیسی مقاله The use MOF-508a as sensing component for the precise discerning of bisphenol A via the electrochemical technique and its synthesis by a simple method were reported in the present study. Scanning electron microscopy (SEM) and x-ray diffraction (XRD) were applied to describe the MOF-508a’s composition and structure. In addition, MOF-508a was exploited so that the glassy carbon electrode could be altered for the bisphenol A’s electrochemical oxidation. The results were indicative of illustration of palpable oxidation peak with lowering over-potential by the designed MOF-508a /GCE. In addition, there was a greater signal response, compared to the unmodified electrode, which was primarily because MOF-508a offered the establishment of large active surface area. As such, this process led to a considerable improvement in the electrochemical surface area. Moreover, adding the elevating bisphenol A concentration resulted in a severe elevation in the anodic peak, presented by the measurements of differential pulse voltammetry (DPV). Furthermore, excellent sensitivity (0.0564 µA.µM-1) with low limit of detection (0.03 µM), a wide linear range (0.1–700.0µM), and high selectivity were shown by the analytical performance of the modified electrode.
