3.2. CMC¨Cmetal ion complexes CMC form polymer complexes with transition metal ions. The binding sites in Cr (III) and Ni (II) complexes were the etheroxygen of the hydroxyl group, while in Cu (II) complexes, the binding sites were the oxygen of ethoxyl groups and the primary alcoholic O atom of glucopyranose rings. These complexes would most likely exhibit an octahedral geometry with Cr (III) and Ni (II), but a square planar configuration in the Cu (II) complex [16]. |
