Physical-chemical and sorption properties of hybrid adsorbents "PP fibers - HIO nanoparticels" and "PP fibers - ferrocyanide nanoparticles of Fe, Ni or Cu" were studied. Sorption experiments with the use of model solutions were made. It is shown that "PP fibers - HIO nanoparticels" is promising hybrid adsorbent for removal of uranium and the transuranium elements; and "PP fibers - ferrocyanide nanoparticles of Fe, Ni or Cu" - for selective removal of cesium ions from radioactive solutions.
