Problems of Monitoring Total Nitrogen in Surface Water by Using Potassium Persulfate Digestion-Uv Spectrophotometry
Xing mei(Chongqing Institute of Environmental Science ,Chongqing 400020)
The tests of potassium persulfate disolving method and reserving time condition proved that thebetter ways were potassium persulfate natural dissolving and reserving time in 3 days when we monitored thetotal nitrogen in surface water by potassium persulfate digestion-Uv spectrophoto metry. Thie paper discussedthe factors which effected the accuracy and precision of total nitrogen tese.
