Dear Sir. I mean using selected props to measure aion concentrations as Cl-, F-, Br, in solutions like water by reading mV of different solutions & standards

Richard A Durst

I'm sorry, but I still don't understand what you're asking. Please clarify, what is the M.voltage and props? Also, what is the experimental setup for your system? It is not clear what the electrode (cathode) is made of and how you can distinguish between the various anions, especially at a cathode. Please provide more information. Thank you.
