Carb<strong>on</strong> hemosorbent VN<str<strong>on</strong>g>II</str<strong>on</strong>g>TU-1 and carb<strong>on</strong> enterosorbent VN<str<strong>on</strong>g>II</str<strong>on</strong>g>TU-2 (nanoporous<br />

(mesoporous) carb<strong>on</strong> sorbents <strong>for</strong> medical purpose) have been developed and obtained in the<br />

Institute of Hydrocarb<strong>on</strong>s Processing SB RAS.<br />

The carb<strong>on</strong> sorbents obtained <strong>on</strong> the base of dispersed carb<strong>on</strong> bel<strong>on</strong>g to mesoporous<br />

sorbents group. The dominati<strong>on</strong> volume of mesopores (the c<strong>on</strong>tents mesopores <strong>on</strong> a surface<br />

up to 80%) allows to carry out effective sorpti<strong>on</strong> of toxic substances with low and average<br />

molecular weight and the molecules size corresp<strong>on</strong>ding to the size of sorbent pores.<br />

Sorpti<strong>on</strong> activity of carb<strong>on</strong> hemosorbent VN<str<strong>on</strong>g>II</str<strong>on</strong>g>TU-1 in relati<strong>on</strong> to chemical standard<br />

markers has been investigated (tab. 1).<br />

The essentially new technology of medical purpose carb<strong>on</strong> materials producti<strong>on</strong> has been<br />

developed and it is completely appropriate to medicine requirements <strong>for</strong> the new generati<strong>on</strong><br />

of sorbents. The given technology has allowed to obtain sorbents with the set physicochemical<br />

properties (tab. 2).<br />
