REMOVAL OF CYANIDE FROM WATER BY REACTION WITH HYDROGEN PEROXIDE AND PHOSPHORIC ACID

摘要

A process is disclosed for the detoxification of effluents containing cyanide by treating said wastewater with a mixture of hydrogen peroxide and phosphoric acid. The molar ratio of phosphoric acid to hydrogen peroxide in the mixture is between 1:100 and 1:3. The consumption of hydrogen peroxide could be lowered by using said mixture compared to hydrogen peroxide alone.
