| Abstract: | The determination method of trace ammonium in high concentration sodium water by 0.45 μm filtration film and gradient elutionion chromatography was established. The selected chromatographic conditions were as follows： IonPac CS16 anion - exchange column, gradient elution with methanesulfonic acid and suppressed conductivity detection. The proposed method was used to determine trace ammonium in high concentration sodium water of processing plant with recoveries of 100.24 - 100.8% ,91.30% - 104.35% respectively. |
