MAGNET-GOVERNED SORBENT AND A METHOD FOR MANUFACTURE THEREOF Russian patent published in 2005 - IPC

FIELD: sorbents in biology.

SUBSTANCE: invention relates to biological and medical areas and can be used for treatment of biological fluids. Sorbent contains nucleus of ferromagnetic with mono- or bilayer envelop or without thereof. Nucleus is made in the form of plate 500 to 5000 μm in size across its plane and with thickness from 0.1 to 1000 μm. Method for manufacture of sorbent is characterized by that powder of iron and/or nickel, and/or titanium, and/or tantalum is vaporized in low-temperature plasma to form product, which is cooled and condensed in gas flow, condensed product is transferred into stabilized dispersion medium. Resulting crystals and microingots are treated to form plates with desired thickness, which are rinsed with distilled water. Weak parts of plates are detached, affected by ultrasound, and dried. Dried plates are fractioned and sorbent nuclei with desired size are isolated and then are layer-by-layer enveloped.

EFFECT: achieved creation of magnet-governed sorbent characterized by essentially larger area of particles for the same mass of nucleus and providing efficient purification of biological fluids.
