METHOD OF SORPTION EXTRACTION OF CESIUM FROM NATURAL AND TECHNOLOGICAL WATERS

摘要

FIELD: purification of water from radioactive isotopes of cesium with the aid of inorganic sorbents. SUBSTANCE: water is purified from cesium-137 by filtration through porous composite material composed of vermiculite and foampolyvinylformal with acetylation degree 50-70 per cent with proportion of components 15-85 : 85-15 correspondingly. EFFECT: enhanced quality of purification, improved hardness of fixing of sorbitized cesium in structure of filtration material. 1 tbl
