I want to do rust removal by electrolysis (sodium carbonate, water solution) Can I use a stainless steel basket as a cathode or will it produce hexavalent chromium ?
I know if I use stainless steel as the anode it does produce hexavalent chromium, but what if it is a stainless cathode ?
I have a solution of sodium carbonate, water and hexavalent chromium. What can I do to eliminate the chromium or make it safe, preferably safe enough to dump in the drain if that is possible.
