FIELD: production of composite sorption materials on base of fibrous carbon material and natural bio-polymer-chitosan.
SUBSTANCE: proposed method includes electrochemical treatment of carbon fibrous material at cathode or anode polarization at interval of potentials of (+1.5) to (-1.5) V relative to comparison silver chloride electrode by 0.05-0.5% chitosan solution in diluted hydrochloric acid in presence of sodium chloride, holding it at preset potential for 20-180 min for forming chitosan film on surface of carbon fibrous material followed by washing the material with water and drying.
EFFECT: possibility of producing materials at varying properties due to performance of process in wider range of polarization potentials.
