Studied on Determination of Total Nitrogen in Water by Flow Injection Analysis

TN is a measure of an important indicator of eutrophication.Subject to the traditional method of high-pressure digestion,temperature and time is difficult to control,and manual operation complex,time-consuming,error,affects the monitoring results.In this paper,flow injection analysis,flow injection to QuickChem 8000 as a platform,through a lot of precision,accuracy and real than the experimental samples to study the water quality of nitrogen compounds in the determination of the application,and then the methods of mathematical statistics(F test,t test) to verify the theoretical feasibility of the method.
