Abstract
The sorption properties of the fibrous sorbents of new types modified with hydroxylamine, ethylene diamine or hexamethylene diamine were studied. The possibility of their use for the disodium 1-(2-pyridylazo)-2-oxynaphthalin-3,6-disulfonate immobilization was shown and the optimal conditions for the determination of iron(III) in water were found.
