Abstract
Organically polluted waters are purified by contacting such waters with a water soluble copper salt catalyst in the liquid phase under oxidizing conditions. In one embodiment, an aqueous stream obtained from the effluent of an oxidative dehydrogenation process containing contaminating oxygen-containing organic materials is subjected to liquid phase oxidizing conditions in the presence of cupric nitrate under conditions providing sufficient cupric ion concentration to convert the water to a potable aqueous product.
