Abstract Modified sorbents with bis-amide groups active in the pH 4–5 range were fabricated from PAN fibres. The characteristics of extraction of copper, nickel, and cobalt ions were investigated, the sorption capacity for these metals was determined, and the possibility of using the new sorbents for fine afterpurification of electroplating wastes and purification of wastewaters from dye plants was investigated. A sorbent which is highly selective for (trivalent) iron ions was fabricated from PAN fibre modified with salicylaldehyde, and the indexes and areas of application were determined, in particular, for purification of sulfate-nickel electroplating solutions in nonferrous metallurgy enterprises.
