Metal ion enrichment of a water-soluble chelating polymer studied by ultrafiltration

Moreno-Villoslada, I; Rivas BL

Abstract

The graphical analysis concerning the metal ion enrichment of water-soluble polymers by the ultrafiltration technique is developed and contrasted with the experimental results obtained with the chelating poly[acrylamide-co-1-(2-hydroxyethyl)aziridine]. An equilibrium is established between the polymer and Cu2+ and a stable blue complex is formed. The compositions of metal ions bound to the polymer and free in solution follow both Langmuir and Freundlich isotherms. From Langmuir isotherm, an apparent formation constant is found with a value of 1.8×10-3M-1. © 2002 Elsevier Science B.V. All rights reserved.
