METHOD FOR PROCESSING OF CARBON MESOPOROUS HEMOSORBENT

摘要

FIELD: chemistry. ^ SUBSTANCE: invention refers to the technology of preparation of carbon sorbents used for hemosorption in the treatment of the diseases accompanied by the accumulation in human organism of certain toxic substances. The method for processing of carbon hemosorbent includes the processing of the porous carbon material with air by the way of contacting with air-water mixture in boiling bed and additional hemosorbent treatment in fixed bed with 4-6% solution of nitric acid fed to the reaction zone in definite time intervals following with air input with volume rate 8 m3/hr for sorbent mixing. The said acid treatment is carried out during 7 hrs, acid/sorbent ratio is 1:(29-32). The obtained sorbent is dried at 200C up to residual residual moisture content 0.2%. ^ EFFECT: preparation of sorbent with high adsorbent activity in relation to nitrogen-containing nonprotein toxic substances such as bilirubin, creatinine, urea. ^ 1 tbl
