摘要：
Divalent metal cations (Mn2+, Co2+, Ni2+ and Cu2+) were separated on HEMA Q-L anion exchanger in the form of their oxalate complexes. The mechanism of the retention of anionic complexes on an anion-exchange column is proposed using the general theory of side equilibria in liquid chromatography. Dependences of the analyte retention on the mobile phase composition were measured and evaluated with the aid of the derived relationships.
