MAGNETICALLY CONTROLLED SORBENT FOR ENDO- AND EXOTOXIN ELIMINATION IN HUMANS Russian patent published in 2014 - IPC C01B31/08 A61K33/26 A61K47/20 A61K47/48 A61P7/00 B82B3/00 B82Y5/00 

FIELD: medicine.

SUBSTANCE: magnetite surface is modified with a compound forming a stable bond to a carrier particle by using surface-active groups giving the selectivity properties, and presented in the form of a coating of normal hydrocarbon chains C₁₂H₂₅ attached to a nucleus by a sulphide bond Fe-S; the above compound providing the bond of iron to the hydrocarbon chain is dodecyl mercaptan. Magnetite is prepared of ferric chloride (II) and ferric chloride (III) by chemical deposition with the concentration of 1 wt % in the solution and a mole ratio of iron (II) and (III) = 2.5, or of ferric sulphate FeSO₄ (II) with adding a mixture of aqueous solution of potassium nitrate KNO₃ and potassium hydroxide KOH at 3 moles of KOH and 0.1 mole of KNO₃ per 1 mole of FeSO₄.

EFFECT: invention provides the sorbent that is used to achieve the effective control of hazardous ingredients of blood plasma.
