The method of the invention provides means of destroying highly stable metal cyanide ions found in a solution, and converting the cyanide to harmless by-products. Contrary to conventional methods which merely complex the cyanide into a mechanically or physically removable complex, the present method destroys the cyanide found in the sample. The invention is directed to a method of destroying cyanide comprising providing a highly alkaline solution containing a metal cyanide ions; and subjecting the solution to electro-oxidation.
L'invention concerne un procédé pour détruire des ions cyanure métalliques hautement stables qui se trouvent dans une solution, et pour convertir le cyanure en des sous-produits inoffensifs. Contrairement aux procédés classiques qui complexent simplement le cyanure en complexe pouvant être retiré mécaniquement ou physiquement, ce procédé détruit le cyanure qui se trouve dans l'échantillon. L'invention concerne un procédé pour détruire du cyanure, comprenant les opérations consistant à se procurer une solution hautement alcaline contenant des ions cyanure métalliques et à soumettre la solution à une électro-oxydation.
