Disposal / Destruction of sodium or potassium cyanide

24/02/2017  And, it is very tough, under normal conditions, to get the cyanide below about 25 ppm with peroxide alone. My approach to concentrated cyanide wastes (2 - 5 g/l) is to take the pH down to about 11 with sodium bicarbonate, add copper ions as a catalyst, then peroxide over a period of hours to bring the cyanide down to about 50 ppm. The endpoint of this treatment stage is signaled by a color change to green, as copper is liberated from its colorless cyanide

The amount of cyanide retained as linamarin is quite high at 25-33%. " Heap fermentation" involves peeling and cutting the roots and leaving them in a small heap for 3-5 days during which some fermentation takes place with liberation of hydrogen cyanide. The roots are then sun dried, pounded and sieved as already described.
