Abstract

A process for working-up solutions, such as radioactive waste, containing ammonium nitrate, which solutions still contain a small amount of heavy metal ions such as uranium and plutonium, is carried out under conditions of reverse current electrolysis, whereby a spatial separation of NH4<+>-ions and NO3<->- ions is effected, NH3 being expelled by an increase in temperature of the solution, and NO3<->-ions, as HNO3, the accumulating heavy metal ions being drawn off for further processing or recycling.
