The radiation resistance of natural zeolite, cation exchange resin, carbon sorbent, and titanium phosphate were investigated, as well the ability to adsorb strontium ions after internal adsorbents irradiation.It is shown, that upon irradiation adsorption properties all these materials are slightly reduced.The only exception with a surface modified NH4OH.Initial residual concentration stable isotopes was measured by direct complexometric titration.Some experiments performed radioactive 90 Sr well.The amount controlled liquid scintillation techniques.The values irradiated non-irradiated samples amorphous determined.The analysis changes under action external conducted method low-temperature nitrogen adsorption-desorption isotherms.The proportion micro mesopores, total area investigated adsorbent, estimated.The pore volume radius calculated DFT BJH methods.A brief comparison methods made.
