SEPARATION OF NaOH FROM SALTS BY WEAK HYDROXY ACIDS

摘要

Promising liquid-liquid extraction chemistry has been identified for the separation of sodium hydroxide from alkaline salt solutions. Recent data show that a putative cation-exchange process using weakly acidic, lipophilic phenols or fluorinated alcohols appears especially attractive for practical use. Specific application of this concept is envisioned for treatment of nuclear waste stored at various United States Department of Energy (US DOE) sites.
