IDENTIFICATION OF THE SUBSTANCE / MIXTURE AND OF THE COMPANY / UNDERTAKING 1.1 Product identifier Substance name : Sodium Cyanide EC Number : 205-599-4 CAS Number : 143-33-9 REACH Registration Number : 01-2119480141-49-0011 1.2 Relevant identified

Disposal / Destruction of sodium or potassium cyanide

24/02/2017  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 complex. Then, I use hypochlorite to bring ...

Cyanide Destruction Methods and Processes

Detoxification processes are used to reduce the concentrations of toxic constituents in tailings streams and process solutions, either by dilution, removal, or conversion to a less toxic chemical form (sometimes referred to as“destruction” or “degradation” in the case of toxic cyanide

Sodium Cyanide SOP

Safety Guideline: Sodium Cyanide Description: Sodium cyanide is a white crystalline solid or powder. It often has a smell like bitter almonds, but not everyone can smell it due to a genetic trait. Physical and Health Hazards: • Sodium Cyanide is a highly toxic chemical compound and deadly human poison by ingestion which requires immediate medical attention in the event of cyanide poisoning ...
