两种不同方法测定硝酸盐氮的比对

Two kinds of different methods of determination of nitrate nitrogen ratio

本文根据实验室多年的实际工作经验,分析和讨论了用离子色谱法和气相分子吸收仪两种方法测定水中硝酸盐氮的含量。其结果显示,两种方法的精密度、准确度和测定结果无显著性差异。

In this paper,according to many years' practical experience of the laboratory,analyzed and discussed with ion chromatography gas phase molecular absorption instrument two methods for determining the content of nitrate nitrogen in water. The result shows that the precision,accuracy,and the determination results of two methods,there was no significant difference can be as a determination method for determination of surface water and groundwater nitrate nitrogen in water
