Ovcharenko Institute of biocolloidal Chemistry NAS of Ukraine popup.description2 Aggregative stability of the water iron-oxygen suspensions, including nanosized, ferrihydrite Fe5O3(OH)9; protolepidocrocite Fe2FeО2(OH)3 and FeFeО2(OH) as well as heavy metals and silver spinel ferrites which formation in water systems on an iron and carbon basis at their contact to air oxygen, had been investigated and methods of their stabilization for the aim of prevention of aggregation, phase transformations and destruction were developed. Dependence of aggregative stability of the specified systems depending on a number of physical and chemical factors, in particular, electrokinetic properties, рН values, concentration of electrolite, etc. are established; the seed nanoparticles ferrihydrite Fe5O3(OH)9; protolepidocrocite Fe2FeО2(OH)3 and FeFeО2(OH); and mechanisms of reorganization of their crystal lattices in the course of formation of monohydrates of iron -FeOOH and -FeOOH, heavy metals and silver spinel ferrites. Methods of the reception of water suspension nanosized particles stability of the specified connections were developed. Product Description popup.authors Лавриненко О. М. Нетреба С.В. Савкін А.Г.
