Many nuclear facilities will have to be decommissioned or dismantled in the near future. Great amounts of solid radioactive waste and waste solution are generated from there mediation of uranium-contaminated soil. If the uranium selectively removed in the waste solution by a resin and desorbed from the resin by a proper reagent, the solution would be reused without an increase of pH to precipitate uranium, and a very small amount of the 2nd waste would be generated. The sorption of uranium from the washing solutions by an ampholyte resin (S-950, Purolite Company) was tested. As a result, 97% of uranium was sorbed on S-950, and 90% of uranium was desorbed from the resin by a batch-type washing with 0.5 M Na2CO3 solution at 60℃.
