SORPTION ACTIVITY OF MAGNETICALLY OPERATED NANOSORBENTS IN BIOLOGICAL MEDIA OF THE HUMAN BODY
ABSTRACT
The work studies the sorption properties of modified magnetite's nano- and microsized particles as well as carbon nanotubes (CNTs) to be used in technologies of extracorporal detoxication of the body fluid media. Sorbent particles are synthesized by different methods. Albumin and dodecyl mercaptan are used as modifiers of the magnetite particle surface. Electronic microscopy is applied in order to investigate the spatial configuration of particles and their agglomerates and to assess their dimensions. The sorption efficiency of sorbents is demonstrated by experiments with blood and lymph plasma taken from 12 donors. The controlled criteria of the sorption capacity of sorbents were biochemical indicators showing the content of their basic constant ingredients in the blood and lymph plasma the concentrations of which can indicate the cellular, organ and general homeostasis of patients with different diseases. The work presents the sorption efficiency of various sorbents, including CNTs, in relation to the blood and lymph plasma ingredients, which is of interest for medical technology applications.
