Information × Registration Number 0210U003593, 0107U005832 , R & D reports Title The investigation of radionuclides complexation processes for their selective recovery from water environs popup.stage_title Head Pshinko Galyna Mykolaivna, Registration Date 11-02-2010 Organization A.V Dumansky Institute of Colloid Chemistry and Water Chemistry popup.description2 Research objects are water environments, muddy connections of U(VI) and heavy metals of Co(II) and Ni(II). A purpose of work is perfection of technology of selective extraction of radionuclides and heavy metals from water environments by baromembrane methods and sorption with the use as sorbents natural and modified by water-dissolved polyethyleneimine of clay minerals. Research methods - spectrophotometry, sciagraphy, sorptive, baromembrane, models of superficial complexing. An apparatus is a spectrophotometer of "Specord UV VIS", pH-meter "ЭВ-74", photometer of КФК-3-01, ultrafiltration, diffractometer of ДРОН-2.0, centrifuge of OС-6М. Theoretical and practical results: selective sorbents is offered on the basis of natural alumosilicates as a matrix for extraction of radionuclides of U(VI) and ions of heavy metals on the example of Co(II) and Ni(II) from water environments with the use of sufficient perspective method of complexing-ultrafiltration. The use of "strong" ligands on-the-spot natural mineral allows selective to extract toxic components, practically not changing salt composition of water. Novelty: modified sorbents is first offered on the basis of polyethyleneimine for extraction of connections of uranium and heavy metals. Industry of the use: preparation of water and treatment of water.
