Potassium Cyanide

CAS RN:151-50-8

Cleanup Methods

Spills of cyanide salts should be immediately and carefully cleaned up by shoveling the material into a proper container. Care must be exercised to minimize any dispersal of cyanide dust into the air. /Cyanide salts/
Waste cyanide salts from case hardening of steel are destroyed by reacting the salts at 650-700 deg C with waste ferric hydroxide sludges from various sources. /cyanide salts/
Removal of copper, nickel, zinc, cadmium and cyanide from plating wastewater by electroflotation. /cyanides/
Keep water away from release. Flush spill area with hypochlorite solution. Cover in noncombustible material for proper disposal. Shovel into suitable dry container. Control runoff and isolate discharged material for proper disposal.
Environmental considerations - Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. /Potassium cyanide, solid/
Environmental considerations - Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash or cement powder. /Potassium cyanide solution/
Environmental considerations - Air spill: Apply water spray or mist to knock down vapors. Vapor knock down water is corrosive or toxic and should be diked for containment. /Potassium cyanide solution; potassium cyanide, solid/
Environmental considerations - Water spill: Add dilute caustic soda (sodium hydroxide). Add calcium hypochlorite ... Adjust pH to neutral (pH= 7). /Potassium cyanide solution; potassium cyanide, solid/
