摘要：

The use of alpha-, beta- and gamma-cyclodextrins as modifiers to the electrophoretic medium containing sodium dodecyl sulphate and a phosphate-borate buffer in the micellar electrokinetic chromatography of polycyclic aromatic hydrocarbons (PAHs) was investigated. The results showed that the migration behaviour of PAHs could be related to their sizes and the cavity sizes of the cyclodextrins. With the addition of gamma-cyclodextrin higher selectivity could be achieved, which consequently resulted in better separation of the seven PAHs investigated.
