It is proposed to combine the mechanical method of purification with a chemical method, i.e., to modify the fibrous sorbents with complex-forming preparations. Such preparations are able to “work” as a result of interaction both with the fiber and with the dye to form a stable complex that retains the dye in the filtering layer of sorbent.
