Cu(II); Co(II) and Ni(II) complexes of chelating resins (CR) bearing iminodiacetate (IDA) ligands were prepared. The CR-metal complexes were characterized by FT-IR spectroscopy; X-ray diffraction (XRD); thermal behavior (TG and DTG) under nitrogen atmosphere; and electron paramagnetic resonance (EPR). FT-IR spectra of the CR-metal complexes showed the characteristic bands of CR were still present but red-shifted after the metal complexation; and new bands assigned to Me-N bonds were observed. Thermal behavior of the metal-CR complexes supported the metal complexation; metal complexation leading to the decrease of the thermal stability of the CR; the lowest thermal stability being found when the highest amount of Cu(II) was loaded. Based on the EPR results and the thermal behavior of Cu(II)-CR complexes; the scheme for the complexation of Cu(II) on the CR was suggested. © 2009 Elsevier Ltd. All rights reserved;
