  • Regeneration of nitrous acid by oxidation with direct application of heated nitric acid
    Patent number: 4925643
    Abstract: A method for regenerating an aqueous liquid comprising nitrous acid and/or oxides of nitrogen is characterized by feeding the liquid to a column such that the liquid descends through the column. An aqueous solution comprising nitric acid is heated to its boiling point such that the heated nitric acid refluxes into the packed column. An oxygen-containing gas is passed into the liquid, whereby the liquid is converted substantially to nitric acid as it descends in the column.

  • Method for the treatment of waste matter
    Patent number: 4874485
    Abstract: An electrochemical method for treating matter particularly waste matter in which AgII ions are primary oxidising species in an aqueous nitric acid electrolyte at about 50.degree.
