摘　　要：A calix[8]arene-bonded gel silica stationary phase(DCABS) was prepared by using coupling reagent(KH560). Its structure was characterized by FTIR, elemental analysis and thermal analysis. The chromatographic performance of DCABS was studied by using different solutes as probes and stationary phases as reference. The results show that the new material has an excellent reversed-phase chromatographic property. The new bonded phase can provide various sites for analytes, such as the hydrophobic interaction, hydrogen-bonding, π-π, electrostatic interactions. Meanwhile, it was observed that the chromatographic performance of DCABS is partially different from CABS because of elimination of the butyl groups.A calix[8]arene-bonded gel silica stationary phase(DCABS) was prepared by using coupling reagent(KH560).
