چکیده

Bisphenol A (2,2-bis (4-hydroxyphenyl) propane, BPA) is an organic compound that widely used in the plastic industry as a monomer for producing epoxy resins and polycarbonate. BPA is ubiquitous since it can be released into the environment from bottles, packaging, and landfill leachates as well as plastics plants. BPA was nonbiodegradable and highly resistant to chemical degradation, so that the concentration of BPA in the environmental is frequently high [1]. BPA is postulated to causereproductive disorders including decrease of sperm quality in humans, birth defects due to its fetal exposure and various kinds of cancers, such as breast, testicular, andprostate cancer [2]. Therefore, a method with high sensitivity, short analysis time, low energy consumption and low cost equipment is required to detection BPA [3].Glassy carbon electrode (GCE) possess many advantages including higher electron rate transfer, wide accessible potential window, low fabrication cost. That for improve sensor electrochemical performance, glassy carbon electrodes have been modified with nanosized materials. In this paper, MXene(Ti3AlC2)/ZnO nanocomposite based electrochemical sensor was fabricated for the determination of BPA, which is very important in the clinical diagnosis. Electrochemical studies were carried out by usingcyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry (CHA). The results demonstrated an enhancement of the corresponding anodic currents measured after modification of the GCE. These results are beneficial for real sample analysis. The sensor worked linearly in the range of 0.1-50.0 μM and had a detection limit of 0.07 μM. The experiments illustrate that MXene(Ti3AlC2)/ZnO nanocomposite is a worthy electrode material which offers a large surface-to-volume ratio and improves the sensitivity.
