Electrolytic treatment of plating wastes |
摘要 |
The known method of removing heavy metal and cyanide ions from plating waste solutions wherein the solution is passed through flow-through, high surface area electrodes to precipitate heavy metal ions and to oxidize cyanide is improved through the use of a novel stationary bed dual electrode capable of reducing heavy metal and cyanide ion concentration. The process promotes economical electrolytic purification because it can be accomplished at relatively high current efficiencies. The metals removed from the solutions are recovered in a concentrated form suitable for purification.
