Fund Project: This work was supported by the National Natural Science Foundation of China.

The present understanding of electrophoretic mobility cannot satisfactorily be used to explain the separation capability of capillary zone electrophoresis for isomeric anions.A molecular shape effect concept was proposed to describe the separation mechanism for isomeric anoins with o-,m-,p-hydroxybenzoates and two food colorants,amaranth and ponceau 4R as examples.
