Popis: A systematization is presented of studies of carbon sorbent functionalization based on chemical modification of the active carbon surface by covalent grafting of macromolecular N-substituted cyclic amines. Thus, porous electron-conducting and luminescent layers grafted onto supports are obtained. The layers can sorb organic compounds. After sorption of acids, hydroxides, and metal salts, the layers become electron- and ion-conducting. Here, hydrogen is formed as in cathodically polarized electrochemical bridges and oxygen is formed as in anodically polarized electrochemical bridges. Principles of layer formation are considered on the surface of the material of cellulose fibers and asbestos cloth, as well as nickel filaments. Specific features of such functionalized sorbents are shown.
