Abstract: Porous zirconia particles, synthesized by polymerization-induced colloid aggregation (PICA)method, were modified with octadecyltrimethoxysilane compounds for reversed-phase high-performanceliquid chromatography.These stationary phases were evaluated in terms of reversed-phase chro-matographic properties with different volume ratos of methanol to water.Stability studies conducted at anextreme pH (pH = 2.0 and pH = 12.0) have shown that octadecyl-zirconia sorbents are no more stablethan ODSunder acidic conditions, but rather stable under basic conditions.The retention of non-polar andslightly polar compounds was quasi-homoenergetic on octadecyl-zirconia stationary phases.

Key words: Zirconia, HPLC, Octadecyl-zirconia bonded stationary phase (ODZ)
