The possibility of concentrating radioactive effluents by reverse osmosis was investigated. Cellulose acetate membranes of the Loeb–Sourirajan type were used, and their performance was evaluated for CsCl and SrCl 2 solutions in concentrations ranging from millimolar to trace level. The applicability of solution–diffusion and irreversible thermodynamic models for predicting solute separation in the above concentration range has been investigated. Some aspects of the selectivity with reference to trace radionuclides are also reported.
