Abstract
A method using capillary zone electrophoresis has been developed for s eparation of a series of isomeric benzene polycarboxylic acids. The se paration was found to depend largely on the geometry of the acids and their degree of ionization as well as on the buffer pH and composition . The presence of additives to the buffer such as cyclodextrin and cat ionic surfactants was found necessary for complete resolution of all t he isomers.
