Abstract
A new material: magnesia-zirconia composite modified by an alkylphosphonate can be used as a reversed-phase stationary phase for high-performance liquid chromatography. The new material was characterized by elemental analysis, FTIR and 13C solid state NMR spectrometry. The pH stability of the new material was investigated using biphenyl and N,N′-dimethylaniline as probes with methanol-water (60:40, v/v) as a mobile phase, after the column was continuously purged with solutions at extreme pH 2 and pH 11. The chromatographic performance of the new material was studied by using polycyclic aromatic hydrocarbons (PAHs) and basic compounds as probes. The results indicate that the new material is of high pH stability and can be used for separation of PAHs and basic compounds.
