| 摘 要： | 用离子色谱法检测水中总氮，检测波长为205nm，整个分析过程仅需7min。方法的检出限为0．03mg／L．测定结果的相对标准偏差为2．1％～3．5％(n=7)，加标回收率为99．0％～103．5％。用离子色谱法和分光光度法对水样进行测定，两种方法测定结果的相对偏差不大于2．1％。

| Abstract: | The total nitrogen in water was determined by ion chromatography with the detection wavelength of 205 nm. The whole procedure of determination could be completed within 7 min. The detection limit was 0.03 mg/mL. The recovery was 99.0%~103.5% with the relative standard deviation of 2.1%~3.5%(n=7).The relative deviation between ion chromatography and spectrophotometry was not more than 2.1%. |
