By using flow injection analyzer, the experiment of determination of total nitrogen in surface water was car- riedout, and the results of the method detection limit, blank value, the correlation coefficient of standard curve, water re- covery and the accuracy and precision were satisfactory, and the alkaline potassium persulfate digesti metric method the comparison test showed no significant difference. This method had the advantages rapid and high efficiency, and can handle a large number of samples. on UV spectrophoto- of simple operation,
