In this study, (sodium alginate (NaAlg)/acrylamide (AAm)) interpenetrating polymer networks (IPN) have been prepared at the fixed composition where the sodium alginate composition is 3% (w/v) in 50% (w/v) acrylamide solutions. This solution has been irradiated in Co-60-gamma source at different doses. The complexation between (NaAlg/AAm)IPN and metal ion solutions was investigated and their complex stoichiometries were calculated. The spectroscopic analysis of (NaAlg/AAm)IPN-metal ion complexes were performed. The luminescence proper-ties of (NaAlg/AAm)IPN-metal ion systems were investigated and the emission and excitation spectra of these IPN solutions were obtained. (c) 2005 Elsevier B.V.
