摘要：

Inorganic anions were determined using capillary zone electrophoresis with UV detection. 1,2-Dihydroxybenzene-3,5-disulphonic acid disodium salt (Tiron) was used as the electrolyte. The determination of vanadate as the analyte ion resulted in two peaks which depended on the pH of the analyte solution. The two vanadate peaks showed opposite behaviour. A pH range of 2.3-11.8 was investigated. The relative standard deviation of the peak areas was 8%. Spectroscopic investigations showed that the vanadate anions interact with the electrolyte.
