We examined eluting behaviors for cationic complexes with the eluting cations. Retention volumes of hydrophilic complexes when eluted by the high concentration of aqueous KCl, NaCl and NH4Cl solutions, have been increased in the order NH4+ > Na+ > K+, but in the low concentration, retention volumes of hydrophilic complexes bave been increased in the order Na+ > NH4+ > K+. On the order hand, retention volumes of hydrophobic complexes when eluted by aqueous KCl, NaCl and NH4Cl solutions, have been increased in the order NH4+ > Na+ > K+ in the whole concentration range. And we examined eluting behaviors for cationic complexes with the eluting anions. Hydrophilic complexes were associated more strongly with chloride ion among halide ions. However, hydrophobic complexes were associated more strongly with iodide ion. Sulfate ion, a highly hydrated anion, was associated more strongly with hydrophilic complexes than with hydrophobic complexes.
