Abstract
A process for decontamination or utilization of the system based on concentrated nitrate acid, containing hydrogen fluoride and orthophosphoric acid, consists in decreasing of concentration of nitrate acid, which is followed by hydration of nitrogen oxides, leading to heavy contolled nitrogen oxide release to the atmosphere. Besides with the purpose of substantial improvement of ecological environment decontamination or utilization of the system is carried out from solutions of HNOconcentration from 90 to 98 %.
