Cyanide Destruction Methods and Processes

Therefore, a number of micro-organisms and their enzymes have the ability to degrade cyanide and metal cyanide complexes (also stable iron cyanide complexes) into less toxic compound like ammonia, formic acid and formamide Microbes can utilise these compounds as a source of nitrogen and carbon for their own growth Reed beds are particularly effective in using cyanide and taking up heavy metals In …

Using hypochlorite to destruct cyanide - Finishing

The primary cyanide destruction must be done at high pH, 105 or greater This will completely destroy all non-complexed cyanide, leaving cyanate The secondary stage, if done, is the oxidation of cyanate to carbon dioxide and nitrogen This is done at a pH of 8 to 85, but it is very dangerous to reduce the pH of a cyanide-bearing waste, as previously noted This cyanate oxidation process takes time, figure an hour
