Abstract

The synthesis of two copolymers of poly[acrylamide-co-(N-(hydroxymethyl)acrylamide)] is described. Polymer analogous reactions have been used as well as direct radical polymerization. The two copolymers have been fractionated and ultrafiltered in the presence of Cu(2+), Cd(2+), Co(2+), Ni(2+), Pb(2+), Zn(2+), and an excess of Na(+). It has been found that N(+) ions do not interact with the copolymers. The effect of the different composition of the copolymers is noted in the study of Cu(2+) and Pb(2+), but there is no difference in the retention profiles obtained for the rest of the metal ions.
