CAPILLARY ION ELECTROPHORESIS, AN ENVIRONMENTAL METHOD FOR THE DETERMINATION OF ANIONS IN WATER

Capillary ion electrophoresis has recently been introduced as a new separations technique for the analysis of inorganic anions. Among its many attributes are rapid, highly efficient separations with different selectivities (compared to ion chromatography), simplicity, and economy. This paper demonstrates the ability of capillary ion electrophoresis to analyze primary and secondary anionic contaminants as well as other ions of environmental concern in drinking water, groundwater, and wastewater. Analysis time is less than five minutes. A comparison of the data to ion chromatography shows excellent correlation.
