Potato starch grafted acrylamide copolymers with weight ratio of acrylamide (AAm) to acrylic acid (AA) of 2 : 1, crosslinked with three acrylic compounds at various concentrations, were prepared. 2,2’-azobis(2-methylpropionamidine) dihydrochloride was used as a radical initiator. Starch copolymers were characterized by infrared spectroscopy, differential scanning calorimetry and rheoviscometry. The Fe3+and Cu2+ cations sorption properties were analyzed using spectrophotometric method. Also, water absorption and swelling tests were performed.
