Research on self-made zinc ion microfluidic chip detection system based on all solid state ion selective electrodetrode

Abstract

This paper first prepared and characterized an all solid zinc ion selective electrode using electrode deposition, and further established a microfluidic chip system integrating zinc ion ASS-ISE and a self-made potential detection device. The stability of the self-made potential detection device was verified by comparing it with traditional electrochemical workstations. The accuracy of the microfluidic chip detection system was verified through comparative testing with traditional atomic absorption spectrophotometry (AAS). The experimental results show that the accuracy and stability of the microfluidic chip system integrated with ASS-ISE and self-made potential detection device meet the requirements of on-site rapid detection.
