The catalytic activity for the decomposition of hydrogen peroxide by anion-exchangers modified with metal complexes of thiacalix[4]arenetetrasulfonate (Me^<n+>-TCAS[4], Me^<n+>=Mn^<3+>, Mn^<2+>, Fe^<3+>, Co^<3+>, Co^<2+>, Cu^<2+>, Zn^<2+> and Ni^<2+>) was investigated. As a reference, calix[4]arenetetrasulfonate, calix[6]arenehexasulfonate and calix[8]-areneoctasulfonate were also examined. Mn^<3+>- and Fe^<3+>-TCAS[4] on the modified anion-exchangers showed high catalytic activity in alkaline buffer solutions among metal complexes tested. Mn^<3+>- and Fe^<3+>-TCAS[4] on the modified anion-exchangers exhibited high and constant levels of catalytic activity even after having been used 5 times, and showed catalytic activity in the presence of an excess of H_2O_2 over Mn^<3+>- and Fe^<3+>-TCAS[4] on the modified anion-exchangers. Only Mn^<3+>-TCAS[4] on the modified anion-exchangers exhibited high catalytic activity at around a neutral pH.
