    • Cyanide Treatment with Hydrogen Peroxide USP

      Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination.

    • Hydrogen cyanide Wikipedia

      Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. A minor tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a pK a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN . A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid.
