Extrinsic Use of Ion Exchange Resins in Radiochemistry and Health Physics

A review is presented on the study of the extrinsic use of ion exchange resins in the fields of radiochemical analysis and health physics.A new series of adsorbents for radionuclides in aqueous solutions has been synthesized, composed of an ion exchange resin and an inorganic metal salt. The resins possess the properties of both the constituent metal salt and the on exchange resin, and have been tentatively termed "metal salt-ion exchange resins".As an extention, one or more kinds of insoluble metal salts could be incorporated simultaneously in one ion exchange resin matrix, by utilizing the residual ion exchange capacity of the resin. These products have been named "multi-loaded metal salt-ion exchange resin". The multi-loaded metal salt-ion exchange resin can be classified into two categories: (a) multi-loaded single metal salt-ion exchange resin, which contains only one metal salt in an ion exchange resin, and (b) multi-loaded composite metal salts-ion exchange resin, which contains two or more different metal salts in a resin.A description is given of the methods of preparing the resins, and of their properties, as well as some applications.
