Ultraviolet spectrophotometric studies of the reactivity of a water‐soluble polymer containing pendant 8‐hydroxyquinoline moieties with metal ions

摘要

AbstractThe water‐soluble polymer4containing pendant 8‐hydroxyquinoline (oxine) moieties was prepared and its reactivity with metal ions was studied by means of ultraviolet (UV) spectrophotometry. Polymer4was 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 compound3except for the Mg2+complex. Polymer4hardly reacts with Mg2+, while model compound3forms a 1 : 1 mol/mol complex. The stability of the complexes of polymer4with metal ions was found to decrease in the following order: Cu2+>Ni2+>Zn2+>Cd2+>Hg2+>M
