Description
The chemical reactivity of nanostructural clinoptilolite and g-hematite which have highly selective for 132Cs sorption from polyethylene surface and for liquid environments are studied. There are different components besides clinoptilolite and g-hematite were chosen to examine as model of deactivation agents for 132Cs sorption. Photon activation analysis was used for study of element composition in samples of natural clinoptilolite and hematite. The chemiluminescence method was used for definition of chemical reactivity of iron-exchanged form of the clinoptilolite to produce hydroxyl radicals from H2O2 (Fenton reaction). The formation of volatile compounds in process of 132Cs sorption was detected . The deactivation agent on basic of thermo modified clinoptilolite with g-hematite nanoparticles was shown the highly synergistic effect for 132Cs sorption from polyethylene surface and for liquid system.
