A Ce 3+ Modified electrode for detection and detection method

Abstract

The application discloses a kind of Ce 3+ The application discloses a modified electrode and a detection method, and belongs to the technical field of water quality detection.The application replaces the traditional three-electrode system with a laser-induced graphene integrated electrode, modifies Ag / MnO2@ZnMOF to the working electrode area, and then prepares an Ag / MnO2@ZnMOF / ILIG sensor.The sensor has higher sensitivity and excellent conductivity, significantly reduces the cost of electrochemical detection, and has the characteristics of portability and flexibility, providing a new possibility and approach for rapid on-site detection of Ce 3+ ions.The MnO2 nanoparticles have a large specific surface area and catalytic activity, amplify the response signal of the prepared sensor.The modification of AgNPs enhances the conductivity of the electrode, accelerates the electron transfer on the electrode surface, and the ZnMOF has high porosity and high specific surface area, which can provide more active adsorption sites for target substances during the reaction process.The modification of MnO2 nanoparticles further improves the specific surface area and electrocatalytic activity.
