| Abstract |
The evaluation addresses the waste reduction and economics of an electrodialytic process that can be used to selectively remove impurities that build up in chromic acid solutions with use. The removal of impurities extends the useful life of the chromic acid solution and reduces periodic replacement of the solution. The electrodialytic units tested in this evaluation were manufactured by Ionsep(TM). The units were tested at SL Modern Hard Chrome in Camden, New Jersey, for a hard chromium plating solution and at Paramax in St. Paul, Minnesota, for a chromic acid solution etching copper from printed wire boards. |
