Preparation and evaluation of C60 bonded silica phase for high performance liquid chromatography]
C_(60)键合硅胶液相色谱固定相的合成及其性能评价

C60 was chemically attached to gamma-(ethylenediamino) propylsilyl-bonded silica as a stationary phase for liquid chromatography. The new stationary phase was used to investigate the separations of polycyclic aromatic hydrocarbons (PAHs) and tert-butylcalixn]arenes. The elution order of PAHs was found to be similar to that on octadecylsilica (ODS); the elution order of tert-butylcalixn]arenes was found to be tert-butylcalix8]arene, tert-butylcalix4]arene and tert-butylcalix6]arene with 1%(V/V) isopropanol/cyclohexane as a mobile phase.
