水中总氮因水样浑浊导致波长275 nm吸光度高而无法测定的解决办法

The solution that total nitrogen in water can not be determined due to turbidity of water sample and high absorbance at 275 nm

在水质总氮的分析中,常常遇到雨季水样浑浊而无法测定浓度的情况。针对这一问题,本文进行了实验研究,并作了比对分析测试,找到了解决该问题的办法,为水中总氮的测定提供了具有参考价值的研究资料。

In the analysis of total nitrogen in water quality,we often encounter the turbidity of water samples in rainy season,which makes it impossible to determine the concentration.In view of this problem,this paper makes an experimental study,makes a comparative analysis and test,and finds a way to solve this problem.The research data with reference value are put forward for the determination of total nitrogen in water.
