Hello, I'm trying to fabricate a thin electrode with stranded Ag/AgCl wires for microfluidics. We purchased 100µm diameter pure silver wires, and based on a previous paper they mentioned Ag/AgCl wires are fabricated by soaking the Ag wires in a bleaching agent for more than an hour and washed by ultrapure water.
I didn't find any additional detailed information of the procedure regarding this bleaching agent and protocol, can anyone share some knowledge on this please? Thanks very much! I'm really not familiar with this.
Dear Haokang Zhang you can find here how to fabricate the Ag/AgCl electrode:
https://www.tau.ac.il/~advanal/ReferenceElectrode.htm#:~:text=Procedure%20for%20coating%20the%20silver,is%20formed%20on%20the%20silver.
You can also find several fabrication methods in wikipedia:
https://en.wikipedia.org/wiki/Silver_chloride_electrode
" The electrode is a silver wire that is coated with a thin layer of silver chloride, either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid or electrochemically by oxidising the silver in a chloride solution."
Hope it helps!
