  • system in cyanide solution

    Sodium Cyanide Solution Using sodium cyanide solution also eliminates the use of chemicals, such as caustic soda, to maintain a stable pH level when dissolving solid sodium cyanide. Water quality, in particular salinity, can significantly destabilise the pH balance in the dissolution process. Get price.

  • Implementation Guidance | International Cyanide Management

    The pH of a solution containing cyanide significantly affects the amount of evolved hydrogen cyanide and the potential for workers to be exposed to toxic concentrations of hydrogen cyanide gas. In aqueous solution, the cyanide ion hydrolyzes to form hydrogen cyanide. At a pH of 9.3 - 9.5, the cyanide ion, and hydrogen cyanide are at equilibrium.

  • Wastewater treatment issues: Cyanide destruction questions

    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. However cyanate is also toxic (not as much, but still), but I read that you can transform them into NH3 and CO2 by adding a strong inorganic acid to cyanates ( bringing to pH =2).
