When the total nitrogen in source water is examined, it is found the water samples with high turbidity give strong disturbance at 275 nm. Through comparing the four ways of the samples treatment,we found one of them is the most effective to reduce the disturbance, that is letting the samples which have been persulfated stand for 15 min,then centrifuging them at the rate of 2 000 r/min to reduce the disturbance as well as turbidity.
Key words： total nitrogen; disturbance; turbidity
