Abstract
A method for the synthesis of the application material for medical purposes based on the carbon hemosorbent is described. The chemical modification of a carbon material was performed via impregnation by azobisisobutyric acid dinitrile (DINIZ) in monomer N-vinylpyrrolidone (VP) with the subsequent polymerization. Selecting the optimal parameters of the modification that allow applying up to 8–15 mass % of poly-N-vinylpyrrolidone (PVP) onto the carbon sorbent is described in detail. As the general analysis we used a thermal method that provides monitoring the VP polymerization process on the carbon material. The proposed method for the synthesis of PVP on the surface of the carbon sorbent was compared with alternative methods of PVP preparation on the surface of different nature carriers. The analysis of the physicochemical properties of the studied sorbents is presented. The reported results of microbiological studies have demonstrated the possibility of using carbon sorbents for the vulnerosorption.
