A new rapid method for the analysis of chromate ion in water by using high performance capillary electrophoresis is described. The detection limit is 1 .0 μg/ml by using 100 m mol/1 Tris-HCI buffer containing 2 m mol/l 1,6-hexanediamine which was used as an electroosmosis modifier to improve the separation and detection sensitivity.
