Adsorption of cyanocobalamine (vitamin B ) on activated carbon, a molding of the Astrakhan region and the modified sorbent of CB-1-K is studied. Comparative studying of sorption of a component on considered sorbents is carried out. Isotherms of static sorption of cyanocobalamine (vitamin B ) from water solutions are presented, change of an enthalpy (∆H), isobaric and isothermal potential (∆G) and entropy (∆S) of sorption are calculated. The kinetics of sorption of cyanocobalamine (vitamin B ) from water solutions is calculated. The new modified sorbent (CB-1-K) on the basis of the molding of the Astrakhan region representing absorber, capable to delete sour gases, heavy metals, various organic and inorganic compounds from air and water is received, without doing harm to health of the person. The main physico-chemical and adsorption-structural characteristics the obtained sorbent are investigated: porosity sorbent on from acetone, total volume of the pore water, moisture content, pH water suspension, bulk density, abrasion, as well as the specific surface through to study the adsorption of isopropanol from the solutions of different concentrations.
