METHOD FOR RECOVERING NITRATE IONS AS NITRIC ACID FROM NUCLEAR INDUSTRY EFFLUENTS

摘要

The invention relates to a process for the recovery, in the form of nitric acid, of the nitrate ions contained in the aqueous effluents of the nuclear industry, by thermal decomposition of these nitrate ions in solution and recovery in an aqueous medium of the NO x vapors generated. by this heat treatment. The nitric acid thus produced is intended to be recycled in the nuclear industry.
