The aim of work is establishment of colloid-chemical features and terms of passing of adsorption-desorption processes in the model dispersible systems for development of effective methods of decontamination of objects of environment. Research methods - physical, physico-chemical and chemical. Processes of interaction of uranium(VI), thorium(IV) and cerium(III) with mineral compounds of soils - clay minerals were investigated, on surface of which natural organic matters and aluminium or iron hydroxides are precipitated, influence of soluble natural and technogenic complexants on these processes is set . The processes of extraction of radionuclides from the objects of environment by complexants were considered , the prospect of application of natural and modified by organic polymers alumosilikates at cleaning of water environments was rotined. The novelty of work is expansion of pictures of migratory behaviours of radionuclides in an environment, and also scientific ground of choice of methods and terms of cleaning of soils and water environments from radionuclides. An application domain is a guard of environment. Product Description popup.authors Боголєпов Андрій Анатолійович Кобець Світлана Олексіївна Тимошенко Тетяна Григорівна popup.nrat_date 2020-04-02 Close
