摘要：

The water-soluble polymer 4 containing pendant 8-hydroxyquinoline (oxine) moieties was prepared and its reactivity with metal ions was studied by means of ultraviolet (UV) spectrophotometry. Polymer 4 was found to form complexes with metal ions in a mole ratio of 2:1 (oxine: metal), which is also obtained for the metal complexes of model compound 3 except for the Mg2+ complex. Polymer 4 hardly reacts with Mg2+, while model compound 3 forms a 1:1 mol/mol complex. The stability of the complexes of polymer 4 with metal ions was found to decrease in the following order: Cu2+ > Ni2+ > Zn2+ > Cd2+ > Hg2+ > Mg2+.
