Comparison Study on Measuring Ammonia and Nitrogen in Surface Water by Flow Injection and Nessler's Reagent

Abstract:

This paper compared the measurement of ammonia and nitrogen in surface water by spectrophotometry and flow injection analysis, and the results indicate: Nessler method detection range of 0.02~2.0 mg/L, and detection limit is 0.02mg/L; flow injection detection range 0.01~ 10mg/L, and the detection limit is 0.001mg/L, 50 samples analyzed rate is 50 samples/h; flow injection is simple and in good linearity, and the sensitivity, precision and accuracy can meet the analytical requirement with better analysis speed, low consumption of reagents and samples, which is a sensitive, selective and friendly analysis method, which will be the future development trend.
