紫外分光光度法测定地下水中NO_3^-—N的含量

Determination of NO_3^--N in Ground Water by Ultraviolet Spectro Photometric Method

饮用水中NO3--N的含量对人体有重要影响,因此测定地下水中NO3--N的含量具有重要意义。本文用UA-1600紫外可见分光光度计,通过标准曲线法,在204nm波长处测定地下水中硝酸盐氮的含量。

Nitrogen is one of the elements full of nutrition in water. The nitrate-nitrogen in drinkingwater has vital infuence onhuman beings,so determining the content of nitrate - nitrogen in ground water has vital significance. In this paper the author measyres the content of nitrate - nnitrogen in ground water by standard curve method at 220nm wave length by UV-1600 spectrophotometer.
