FIELD: inorganic chemistry, pharmacy. SUBSTANCE: highly dispersed powder Ferrum reductum is subjected for fractionation in inert gas flow at the rate 0.02-1.00 m/s at the range of magnetic field intensity 10-103 A/m. Then iron particles are subjected for thermic treatment at 1000-1500 C in inert gas flow containing microparticles of carbon and/or silicon oxide, and/or aluminium oxide. Then surface of ferrosorbent particles is covered with biologically active compounds - food proteins or dextran, or drugs, or antibodies. EFFECT: improved method of producing. 4 cl, 1 tbl
