How is cyanide waste disposed of?
Thoroughly rinse empty containers with large amounts of water. The rinse should be used in the cyanide process. Puncture or crush empty containers and dispose of them at approved waste disposal sites.
Is cyanide a hazardous waste?
According to property (5) under 261.23, a waste is hazardous if it is a cyanide- or sulfide-bearing waste which generates toxic gases or vapors at a quantity sufficient to present a health danger.
How do you dispose of sodium cyanide?
Dispose of the rinse as hazardous waste. Or: Rinse the glassware three times with dilute sodium hydroxide solution (0.1 to 1 mM) in the hood and collect the rinse as cyanide waste. After rinsing, clean the glassware with soap and water.
How do you dispose of poisonous substances?
Toxic wastes can be disposed of by depositing them in specially built landfills or by incineration, depending on their chemical type. With land disposal, waste is buried in landfills that should be “permanently” sealed to contain the waste.
Does bleach neutralize cyanide?
Cyanide safety, cyanide detectors, antidotes. As far as I know, you can neutralize cyanide with a Sodium Hypochlorite solution (Bleach) under basic conditions (pH = 9-11) which will oxidize cyanides (CN-) ions into cyanates (CNO-) ions.
How are acid and cyanide disposed?
Is cyanide gas flammable?
Hydrogen cyanide (AC) is a pale blue or colorless liquid below 78° F and a colorless gas at higher temperatures. It has a bitter almond odor and is highly volatile and flammable at room temperature.

Is sodium cyanide soluble in water?
Some simple cyanides are soluble in water (sodium cyanide, NaCN; potassium cyanide, KCN; and calcium cyanide, Ca(CN)2), while others are sparingly soluble or almost insoluble (copper (I) cyanide, CuCN).
What are the examples of hazardous waste?
Some examples of hazardous wastes you may find around your house include(1):
- antifreeze.
- batteries.
- brake fluid.
- chemical strippers.
- chlorine bleach.
- contact cement.
- drain cleaners.
- fire extinguishers.
What is the difference between free cyanide and total cyanide?
Total Cyanide is also sometimes referred to as Strong Acid Dissociable (SAD) Cyanide. Free cyanide refers to either molecular hydrogen cyanide (HCN) or ionic cyanide (CN-). At a pH of 7 or less in water, free cyanide is present entirely as HCN. Above pH 11, free cyanide exists entirely as CN-.
