The chemical reactivity of nanostructural clinoptilolite and γ-hematite which have highly selective for ¹³²Cs sorption from polyethylene surface and for liquid environments are studied. There are different components besides clinoptilolite and γ-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 thermomodified clinoptilolite with γ-hematite nanoparticles was shown the highly synergistic effect for ¹³²Cs sorption from polyethylene surface and for liquid system.
