Method of oxidation

Electrochemical oxidation of matter

Disposal of organic materials encased in metal

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.

Regeneration of nitrous acid by oxidation with direct application of

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. C., produce secondary oxidising species through interaction with the electrolyte and which decompose the waste matter. AgI ions produced in the course of the decomposition are converted back to AgII electrochemically.
