Abstract: 3-(Aza-18-crown-6)propylsily bonded silica stationary phase for high performance liquid chromatography was prepared via two-step solid-liquid reaction as follows: porous silica(5～7 μm) was activated using γ-chloropropyl triethoxysilane, then reacted with sodium secondary amine salt of monoaza-18-crown-6. The bonded stationary phase shows a good complexing ability with sodium and potassium ions. The chromatographic behavior of disubstituted benzenes and amino acids was investigated on the bonded stationary phase with various mobile phases.

Key words: HPLC, Bonded silica stationary phase, Aza crown ether
