Abstract
ABSTRACT This paper reports a method for preparation of functional derivative – poly(N-2-sulfoethyl)allylamine – obtained when treating poly(allylamine) with sodium vinylsulfonate, and allowing for the complete functionalization of the amino groups. The composition and the structure of the products of the polymer transformation were studied using the elemental analysis, FT-IR spectroscopy, and 1H NMR spectroscopy. In order to obtain the sorption material, it is necessary to use epichlorohydrin, which enables the effective cross-linking of the macromolecule, vs. glutaraldehyde. The sorbent based on the sulfoethylated poly(allylamine) selectively removes silver(I) from its ammonium acetate buffer solution having the рН value from 6.0 to 6.5 and containing some other transition and alkaline earth metal ions.
