The adsorption-desorption behaviors of hydrophobic anion on the solid phase coated with redox-active metal complexes (ML2+/0 ; M, CoIII/II ; L−, pyridylazo compounds) were investigated. The combination of a cobalt complex of poly vinyl phenol introduced with a 2-pyridylazo group and a solid-phase extraction cartridge packed with styrene-divinyl benzene copolymer sorbent showed the highest adsorption capacity for methyl orange as a hydrophobic anion. The percentage adsorption of methyl orange (1.0 μmol) on this solid phase was more than 99%, even in the presence of a 100-fold stoichiometric excess of coexisting anions (ClO4−, Cl−). Methyl orange molecules were desorbed by reducing the cobalt complexes in the solid phase with a 1.0 × 10−2 M ascorbic acid solution.
