| Abstract: | Apply Ion chromatography method on determining ammonia nitrogen in water quality Sample,which has more convienient operation, quicker, less interferent, less measuring quantity, less reagent and higher sensitivity. The linear range of determination is from 0.002mg/L to 1000mg/L, the detected limit of this method is 0.004mg/L while repeatability less than 1.5% and mark-on recovery ranging from 93.8% to 102.5%, and reduction of secondary pollution come a satisfactory conclusion. |
