摘要：

The chromatographic behaviour of alkali and alkaline earth metal ions on a silica-bonded macrocyclic calix[4]arene tetradiethylamide phase is reported. Selective retention of Na+ over other alkali metal ions and of Ca2+ over Mg2+ ions is found using water as the mobile phase and conductivity detection. A series of amino acid ester hydrochlorides are shown to be retained in order of their hydrophobicity on a silica bonded calix[4]arene tetraester phase with aqueous mobile phases containing lithium perchlorate and acetonitrile. Retention of metal ions and organic solutes on these new silica-bonded functionalised calixarene phases is dependent on the organic modifier concentration.
