| Abstract: | It was proved by the experiment that in the process of determination on total nitrogen in water sample with potassium persulfate digestion - UV spectrophotometer method, it was convient and feasible to use ultra - pure water instead of ammonia - free. Under the optimum conditions, the sample was determined and the result was accurate and reliable; meanwhile the details of the experiment was added. |
