Title: A PROCESS FOR PREPARATION OF COMPOSITE SORBENT FOR REMOVAL CONTAMINANTS FROM WATER
Abstract:
A process for the preparation of high performance composite sorbents suitable for the removal of contaminants namely harmful metals and natural radionuclides from water based on the nanoporous carbon fibers, on which the nano- and microparticles of iron hydrooxide is deposited, and which employs the synergistic effect of large surface of the nano- and microparticles of iron hydrooxide and the fibrous structure of the carrier, while the latter reduces the hydrodynamic resistance to the flow of water, whereas both the efficiency and the capacity of the sorbent in removing contaminants do not depend of the water pH within the practical applicability range.
