FIELD: metallurgy.
SUBSTANCE: invention refers to extraction of niobium (V) from water fluorine-containing solution with the use of sorbents and can be used in non-ferrous and ferrous metallurgy, as well as for cleaning of industrial and domestic sewage systems. Method involves sorption by contact of solution and anionite. At that, sorption is performed at pH=1-4 with AM-2b anionite pre-treated with acid or water, and containing the following exchange groups: -CH2-N(CH3)2, -CH2-N(CH3)3.
EFFECT: providing optimum conditions for quick and effective extraction method of niobium (V) anions from fluoride-containing water solution.
