Abstract
Process for reducing the acid content of a nitric acid solution by using an electrolysis current which is capable of reducing HNO.sub.3 at the cathode. The nitric acid solution is divided into a first volume portion and a second volume portion. The first volume portion is reduced electrolytically to form a reaction product containing ammonium nitrite (AN). The second volume portion is reduced electrolytically to form a reaction product in the form of nitrous gases NO.sub.x, essentially NO and/or NO.sub.2. The reaction products are brought together and reacted at a temperature in the range from 50.degree. C. to below the boiling point of the solution resulting from the bringing together of the reaction products, by heating the resulting solution.
