STUDY INTO GAMMA AND NEUTRON RADIATION ON SORPTION PROPERTIES OF SOME NATURAL AND SYNTHETIC SORBENTS

Influence of gamma radiation and neutrons on sorption properties of some natural and synthetic sorbents has been studied. It found that the adsorption capacity of clynoptylolyte and phosphor-chloride cellulose in respect to uranium isotope after irradiation in the flow of thermal neutrons (2.5·1010 neutron/cm-1) rises 2.49 and 2.15 times respectively. Under the effect of ionizing irradiation and products of disintegration in clynoptylolyte and phosphor-chloride cellulose there occurs the formation of new active centers of adsorption. At relatively higher doses of irradiation the adsorption capacity of  phosphor-chloride cellulose drops following the radiation-chemical destruction.
Keywords: sorption, clynoptylolyte, cellulose, uranium, radium, gamma and neutron radiation.
