Abstract
The sorption properties of new iminodiacetate fibrous cation exchanger FIBAN XC-1 synthesized on a chemically resistant matrix of polypropylene fiber with a grafted copolymer of styrene and divinylbenzene, which can withstand elevated temperatures and aggressive environments, were studied. It was shown that the fibrous chelate ion exchanger FIBAN XC-1 is an effective sorbent of heavy and non-ferrous metals from multi-ionic aqueous solutions under static and dynamic conditions. It was found that the cation exchanger operates at high speeds up to 20 column volumes / min in water purification from copper and lead ions (purification from Cu2+ – 82 % and purification from Pb2+– 65 %). It was found that the fibrous chelate ion exchanger FIBAN XC-1 is easily regenerated and does not lose its sorption and mechanical properties in the sorption– regeneration cycles.
