Fabrication of MnO2 - based electrochemical electrodes for the determination of copper (II) ion in water
Abstract
Porous MnO2 with a hexagonal crystalline structure was facilely prepared at a low hydrothermal temperature of 90°C, without using any template or capping agent. The as-prepared MnO2 only presented an exceptional electrocatalytic ability by the typical amperometric detection of copper (II) in the presence of super P carbon black as conducting agent, and Nafion as binder. In the present work, to evaluate the detection ability of copper (II) of the MnO2, the graphite plate electrodes (GPE) were modified with MnO2 microflowers and super P carbon and used as electrochemical electrodes for the determanation of copper (II) present in water sources. From the measured results, the fabricated electrodes with excellent copper detection and rapid response demonstrated has high application potential for electrochemical sensors in detection of copper in water resources.Downloads
