| Abstract: | The content of nitrite nitrogen in Jialing river was quantitatively determined by UV spectrophotometry.By optimization of determination conditions,the optimal testing conditions were as follows:dealing with Jialing river water with Zn(OH)2,1g/L alkaline fuchsin of 2.00mL,reaction time of 20min.The average content of nitrite nitrogen in Jialing river was 2.875mg/L.The method is simple and fast with little interference and safe reagent,and fit for quantitative measurement of nitrogen in water. |
