METHOD FOR EXTRACTING RADIOACTIVE ELEMENTS FROM LIQUID WASTES Russian patent published in 2005 - IPC

Abstract RU 2251168 C2

FIELD: recovery of liquid radioactive wastes.

SUBSTANCE: proposed method includes bringing liquid radioactive wastes in contact with matrix saturated with selective ion-exchange material (solid extracting agent). Glass-crystal material with open porous structure is used as matrix for the purpose. Matrix material is produced from hollow glass-crystal cene spheres formed from mineral particles of volatile ash produced as result of black coal combustion and saturated with selective ion-exchange material.

EFFECT: facilitated procedure of radionuclide extraction.
