FIELD: chemistry.
SUBSTANCE: invention relates to radiochemical technology and can be used in processing of ammonia-containing process solutions and liquid radioactive wastes (LRW) formed during operation radiochemical production. Method for decomposition of ammonium nitrate in radiochemical production process solutions involves heating and correction of solution in nitric acid. Process of decomposition of ammonium nitrate is carried out in a system of nitric and oxalic acids in presence of solid-phase platinum-containing catalyst in dynamic mode in a temperature-controlled column-type apparatus of continuous action.
EFFECT: invention enables quantitative decomposition of ammonium nitrate in process solutions in a wide range of concentrations.
