摘要：Metal complexes the type sodium polyacrylate and copper (PA-Cu) were prepared and studied. The characterization of the two complexes formed was performed by IR spectroscopy. IR spectroscopic investigation by comparing the spectra of the complexes with those ligands only serves to better understand the mechanism by which sodium polyacrylate fixed Cu 2+ ions. Structural changes in the two complexes are observed. Indeed, the regressions of some bands have been observed, indicating the coordination of the COO - group to the metal ion by cation exchange, according to the following reaction: 2COO - + Cu 2+ → [COO] 2 Cu
