摘    要:依据国家标准方法:碱性过硫酸钾-紫外分光光度法(GB1189—89)检测地表水中的总氮,通过实验分析发现,水样的浑浊度对波长在275nm处的吸光度值有严重影响,消解降低水样的浑浊度后,会使275nm处的吸光度值下降。

关 键 词:总氮  浑浊度  干扰

Abstract:The national standard method was used to determine total nitrogen in surface water in this paper.The results showed that the absorption value at the wavelength of 275 nm was lower after reducing turbidity in sample.
Keywords:total nitrogen  turbidity  disturbance
