A Multicolumn Ion Chromatographic Determination of Nitrate and Sulfate in Waters Containing Humic Substances
(1986) In International Journal of Environmental Analytical Chemistry 25(1-3). p.161-171- Abstract
A three-column ion chromatographic system for the removal of humic substances from natural waters, and subsequent on-line concentration and determination of nitrate and sulfate using non-suppressed ion chromatography is presented. Humic substances are removed using disposable adsorption columns packed with chemically bonded amine silica material. The sample is directly transfered to an ion exchange column where the anions are concentrated ca 10 times. After reversing the flow, the ions are transferred to a third column where they are separated and quantified. The detection limit is less than 1 mgL-1 of nitrate or sulfate in water containing 45 mgL-1 of humic acid.
