Abstract

A recently developed process combines sulfur dioxide and air to oxidze cyanide, removing it from industrial waste effluents. The process uses lime for pH control and copper in solution as a catalyst for cyanide oxidation. Significant advantages of the process include thoroughness of cyanide removal, operational simplicity, improved safety and lower reagent requirements. Lower costs are an additional benefit of the process.
