Sorbents that concentrate radioiodide from aqueous alkaline solutions are obtained by depositing finely divided silver in porous materials, in particular in cation exchange resins. Suitalbe materials and procedures for preparing sorbents with capacities up to about 120 mol I per ml sorbent (i.e. 40 mmol I per mol Ag) are discussed.
