Abstract
Abstract Poly(2-acrylamido glycolic acid- co -acrylamide), P(AGA- co -AAm), and poly(2-acrylamido glycolic acid- co -4-acryloylmorpholine), P(AGA- co -AMo), were synthesized by radical polymerization. The water-soluble polymers containing tertiary amine, amide, hydroxyl, and carboxylic acid groups were investigated as polychelatogen, in view of their metal ion binding properties by using the liquid-phase polymer-based retention technique under different experimental conditions. The retention properties for the following metal ions were investigated: Ag + , Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Cd 2+ , Pb 2+ , Al 2+ , Cr 3+ and Fe 3+ . P(AGA- co -AMo) showed a selective retention for tri-valent cation Al 3+ at pH 3, but no retention at higher pH. P(AGA- co -AAm) showed the highest metal ion retention capability, specially at pH 5 and pH 7 with values close to 100% to di-valent cations.
