| Abstract: | This article basically discusses how to determine the total nitrogen in waste water by using Continuous Flow Analysis （CFA）. The muddy water is filtered by enlarging the measuring range to 20 mg/L,and the test results show that the correlation coefficient of this method reaches 0. 9999 and MDL is 0.02mg/1, meanwhile,the standardized recovery rate is between 99.5% and 108% ,and RSD is between 0.2% and 0. 6 %. Thus it is proved that the method can be used to determine the total nitrogen in waste water. |
