Catalytic Activity of Thiacalix[4]arenetetrasulfonate Metal Complexes on Modified Anion-Exchangers for Ascorbic Acid Oxidation

The catalysis of ascorbic acid (AsA) oxidation by anion-exchangers modified with metal complexes of thiacalix[4]arenetetrasulfonate (Me-TCAS[4]A-500, Me=Mn3+, Fe3+, Co3+, Ce4+, Cu2+, Zn2+, Ni2+, and H2) were investigated. Me-TCAS[4]A-500 (Me=Mn3+, Fe3+, Ce4+, and Cu2+) all exhibited the ability to c...
