Abstract:
A combined supported liquid membrane (SLM)/strip dispersion process for the removal and recovery of one or more radionuclides or one or more metals from a feed solution containing the radionuclides comprising(1) treating a feed solution containing one or more radionuclides or one or more metals by passing the feed solution on one side of the SLM embedded in a microporous support material and removing the radionuclides by the use of a strip dispersion on the other side of the SLM, the strip dispersion being formed by dispersing an aqueous strip solution in an organic liquid comprising an extractant using a mixer; and(2) allowing the strip dispersion or a part of the strip dispersion to separate into two phases, the organic liquid phase and the aqueous strip solution phase containing a concentrated radionuclide or metal solution.
