Removing trivalent chromium from chromic acid using hydrogen peroxide

2016-02-04View Original

Thread Content

I have come across three or four articles online on the use of hydrogen peroxide to remove trivalent chromium from chromic acid; adding hydrogen peroxide slowly while electricity is applied can reduce the amount of trivalent chromium in the chromic acid used for electroplating. But I tried several experiments and all failed. Is there anyone who understands this and can give me some advice to figure out what the problem is. Thanks. Everyone is welcome to join the discussion.
