Methods of research - organic synthesis, chemical analysis, mathematical processing of experimental data. Porous bearers based on copolymers of sterol and divinylbenzene and on the base of synthetic nitrogen-containing activated coal from nitrileacrylic acid and divinylbenzene were received. The selective radionuclide's (caesium, strontium, actinides) complexing agents - trialkylphosphine oxides, carbamoylphosphine oxides, crown-ethers and calixarenes used as impregnates for porous bearers were synthesized. Hard extractants for binding radionuclides using the porous bearers worked out were created. Physical chemical characteristics of the bearers and hard extractants obtained were described. The complexing, extraction and sorbtion properties of the obtained compounds to radionuclides were researched.
