Measurement Of Ammonium By Ion Chromatography In High Sodium Concentration, Sharon Klein
Measurement Of Ammonium By Ion Chromatography In High Sodium Concentration, Sharon Klein
The Journal of Undergraduate Research
Chemical analysis of Antarctic ice cores provides valuable information on the history and dynamics of the atmosphere environment. The ice core samples contain trace amounts of ammonium, sodium, and other ionic chemical species, which are usually, measured using ion chromatography. High concentrations of sodium may interfere with the accurate and precise measurement of ammonium, due to insufficient resolution of their chromatographic peaks. The extent of the interference is investigated in this project by quantitative determination of the ammonium concentration in solutions of various ammonium and sodium concentrations. A criterion of 20% relative error of measured ammonium concentration is used to …
