A procedure is developed for the determination of organic amines in potable water and wastewater by capillary electrophoresis. A mixed solution of benzimidazole and tartaric acid is selected as a leading electrolyte for indirect photometric detection. The sample was injected hydrodynamically. The procedure was tested on samples of potable water and wastewater. The accuracy of the results was evaluated by the standard addition method. The analytical range is 0.25-5 mg/L. The analysis time is 4-5 min.
