MEDICAL ADSORBENT AND METHOD FOR ITS OBTAINING Russian patent published in 2017 - IPC A61K33/44 A61P1/16 A61P39/02 B01J20/20 B01J20/30 C01B31/10 

FIELD: medicine.

SUBSTANCE: medical adsorbent contains activated carbon in the form of spherical pellets, obtained by carbonizing and activation of regenerated cellulose in a spherical shape, and having average pore diameter of 1.5 to 2.2 nm, specific BET surface area of 700 to 3000 m²/g, average particle size of 115 to 1002 mcm, oxide content of 0.05 meq/g or more on the surface, and packing density of 0.4 to 0.8 g/ml. Method for adsorbent production comprises the steps of: spherical viscose conversion into regenerated spherical cellulose in an acid precipitation bath, and carbonizing of the resulting regenerated spherical cellulose at a temperature of 300°C to 700°C under a nitrogen atmosphere, and then steam activation at a temperature of 750°C to 1000°C, acid cleaning and heat treatment at a temperature of 500°C to 800°C. It can be used as a therapeutic or prophylactic agent for kidney disease or liver disease for oral administration.

EFFECT: adsorbent has low dosage and excellent adsorption capacity and selective adsorption of toxins, it can shorten the activation time, it is economical and environmentally friendly.
