摘要：

The use of water-soluble calixarene, p-sulfonic calix[4]arene, in capillary electrophoresis, was reported. Successful separations of positional isomers of nitrophenol, benzenediol and aminophenol were obtained with the addition of p-sulfonic calix[4]arene to the running buffer. Efficiency up to 3.0x10(5) plates/m was achieved. The influence of the calixarene concentration was studied and it was found that the resolution increased with the increasing calixarene concentration. The interaction of solutes with calixarene was also discussed. (C) 1998 Elsevier Science B.V.
