Abstract
Aqueous solutions containing, amongst other radiation sources, 10/sup -2/ to 10/sup -7/ mol per litre Pu and/or Np - especially aqueous solutions produced when reprocessing fuel elements, in particular of HTR reactors, e.g. according to the Thorex process - can be cleaned from the two metals without much expenditure by using a separating column: determination of the H/sup +/ ion concentration (0.5-6 mol/litre solution), addition of a stabilizing agent (NaNO/sub 2/ or Fe (NH/sub 2/SO/sub 3/)/sub 2/) and passage across a separating column in which the granulate charge is wetted with a long-chain alkylamine (e.g. trioctylamine) which retains the metal. The production of a charge (of Voltalef UF 300) is described. The process may also be carried out continuously.
