Abstract

Hybrid sorbent on the base of anion-exchange polymeric matrix with HFO for selective sorption of arsenic characterized in that, HFO exists in matrix as particles, which at most are amorphous ferrihydrite, fraction of which is not less than 80%, preferably more than 90% from total mass of HFO. The object of the invention and the technical result achieved with the use of the invention is to develop new hybrid sorbent with HFO with increased sorption kinetics of two arsenic forms As(III) and As(V) simultaneously.
