摘要：

The effect of counter-ion inclusion complex formation on the separation efficiency in electrolyte systems modified with beta-cyclodextrin and its methyl derivatives was studied. On the basis of the analysis of complex-forming equilibria established in the sample mixed zone, it was concluded that an increasing stability of the counter-ion inclusion complex results n a decreased efficiency of the separation process. This was verified experimentally on the set of eleven aliphatic and aromatic acids used as counter-ions in slightly acidic cationic electrolyte systems.
