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

Capillary ion electrophoresis has recently been introduced as a new se parations technique for the analysis of inorganic anions. Among its ma ny attributes are rapid, highly efficient separations with different s electivities (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 othe r ions of environmental concern in drinking water, groundwater, and wa stewater. Analysis time is less than five minutes. A comparison of the data to ion chromatography shows excellent correlation.
