Abstract |
A Dionex Model 10 Ion Chromatograph was evaluated for the measurement of anionic species in water. The theoretical effect of hydrogen ion activity (pH) on the elution time of phosphate and arsenate was tested and empirical selectivity coefficients were determined for the major protolytic species of these acids. Calibration curves were obtained for arsenate, bromide, chloride, nitrate, nitrite, phosphate, selenate, selenite, and sulfate by direct injection of 0.1 mL of standards and, in most cases, by preconcentration of 5 to 50 mL of solution on the ion exchange concentrator columns available from the instrument manufacturer. Detection limits for ions other than chloride were approximately 0.2 micrograms independent of the method of sample introduction. For chloride the detection limit was 2 ng, by direct injection. The concentrator column permitted determination of any of the above ions at concentrations greater than 10 micrograms/L. |
