Description

technical field [0001] The invention relates to an electrode, in particular to a flat-plate working electrode and a manufacturing method thereof. Background technique [0002] Electrochemical detection technology has the advantages of low cost, simple required instruments, high sensitivity, and short analysis time, and has broad application prospects in product inspection, environmental monitoring, medical health and other fields. The working electrode, also known as an electrochemical sensor, is a key component for electrochemical detection. At present, the working electrodes used for electrochemical detection mainly include noble metal electrodes (gold, platinum, palladium, etc.), mercury electrodes (dropping mercury electrodes, hanging mercury electrodes, mercury film electrodes, etc.), carbon-based electrodes (graphite electrodes, glassy carbon electrodes, etc.) , carbon paste electrodes, etc.) and screen-printed electrodes. However, the above-mentioned electrodes have...

AI Technical Summary

Problems solved by technology

However, the above-mentioned electrodes have more or less defects, which greatly limit the application of electrochemical detection in practical work.

For example: noble metal electrodes are relatively expensive; mercury electrodes are highly toxic, and long-term use will cause harm to the environment and operators; carbon-based electrodes require complex and cumbersome pretreatment processes before use, including polishing, grinding, cleaning, aging, etc.; silk screen Printed electrodes require specialized equipment for processing, and their reproducibility is not satisfactory
