| Abstract: | 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. |
