摘　　要：用流动注射-盐酸萘乙二胺分光光度法与碱性过硫酸钾消解紫外分光光度法同时分析已知浓度的样品,两者的不同之处是流动注射为在线消解,碱性过硫酸钾采用高压锅消解,两种实验分析方法都有各自的优点和缺点。使用的仪器设备和试剂都有差异,均适用于地表水、地下水、工业废水和生活污水中的总氮,都能为防治和保护环境污染政策提供有效、真实的建议。Samples with known concentrations were analyzed simultaneously by flow injection analysis(FIA) and N-(1-naphthy1) ethylene diamine dihydrochloride spectrophotometry and potassium persulfate digestion UV spectrophotometric method. The difference between them is flow injection analysis(FIA)and N-(1-naphthy1) ethylene diamine dihydrochloride spectrophotometry is online digestion and potassium persulfate digestion UV spectrophotometric method is the pressure cooker digestion. Both of these two analysis have the advantage and disadvantage. The equipment and reagent they used are different. But both of which are suitable for total nitrogen in surface water, groundwater, industrial wastwater and domestic sewage, providing effective and real suggestions for environmental pollution prevention and protection policies.
