EFFECT OF POLY(ACRYLIC ACID) IN THE METAL ION BINDING ABILITY OF POLY(SODIUM 2-(N-ACRYLAMIDO)-2-METHYL-PROPANESULFONATE)

The binding of Cu2+, Cd2+, Co2+, Pb2+, Zn2+, Ni2+, Cr3+to poly(sodium 2-(N-acrylamido)-2-methyl-propanesulfonate) (PAMPS) in the presence of poly(acrylic acid) (PAA) is studied by diafiltration. It is found an unusual behavior for the polyelectrolyte PAMPS, since it binds irreversibly a fraction of...
