Macromolecular Al(III) complexes with poly(acrylamide) and products of its alkaline hydrolysis

Abstract

The complexation of Al(III) with poly(acrylamide) and its derivatives containing carboxy groups is investigated by pH metry and viscosimetry using computer modeling. The formation of complexes of M:L = 1:1 composition and of different stability is found to be possible in a weakly acidic medium; in neutral and alkaline media, complexes of M:L = 2:2 composition may form with participation of the binuclear Al(III) hydroxo complexes. © 1996 MAEe Cyrillic signK Hayκa/Interperiodica Publishing
