摘要：
Three stationary phases based on silica modified with imidazolium ionic liquids were prepared and characterized for their use in high-performance liquid chromatography. Multiple interactions of separation mechanism of the three stationary phases were studied by using caffeine, theophylline and theobromine. The comparison of differential retentions was established and the hydrophobic interaction of the alkylimidazolium groups showed stronger impact than other interactions in separation of alkaloids. The effects of temperatures and different concentrations of additives in eluent were also investigated. Furthermore, the study of retention mechanism was used to predict the order of elution of cytosine, thymine and guanine successfully.
