Treatment of water containing cyanide |
June 14, 1977 |
| Sodium chloride is added to water which is then passed through at least one electrolytic cell. There, electrolysis of the sodium chloride produces chlorine molecules and sodium hydroxide. The water is then flowed into the presence of metal-cyanide contaminants. The chlorine and caustic |
