Abstract

A stationary phase was prepared by modification of octadecyl silanized silica gels (ODS) with phthalocyanine cobalt (III) for separation of anions. The elution sequence of anions on the column packed with the modified ODS is in the order of Cl^-<NO₃^-<ClO₄^-<I^-<SCN^-<NO₂^-, which was quite different from the elution sequence observed on a conventional anion exchange column. The strong retention of NO₂^- on the column was explained by a result of adsorption experiment of NO₂^- and NO₃^- on the modified ODS.
