| Abstract: | Nessler＇s reagent colorimetric method is the national standard method of determination of ammonia nitrogen in water. The article mainly discusses the Nessler＇s reagent spectrophotometric method for the determination of ammonia nitrogen in water by several influence factors. It also presents the determination process should pay attention to the problem, in order to reduce the absorbance of blank, reduce the analytical error, and improve the accuracy of the test. |
