Apologies if this has been asked already but I couldn't find an answer.
Is there a method to test silver cell electrolyte to monitor its copper content that isn't going to cost a fortune?
I currently only run my cell to purify silver from 98/99% to 999 so I get a reasonable throughput before the electrolyte goes blue and I swap it out. I am currently simply using the colour of the solution to give an educated guess at copper content (and to some extent palladium contamination.) However I am now looking to set up a cell to process 92.5% Stirling. I am told this will be more economical than nitric dissolution (certainly saves alot of time!). My problem is ofcourse that its alot more copper going into the electrolyte and for the economics to work out I want to be getting the most use out of the electrolyte before it is recycled.
I'm guessing I will be able to determine how much copper in solution is to much by experimentation but it's how to quantify copper in solution that is puzzling me at the moment.
