摘要
采用紫外分光光度法对嘉陵江水中亚硝酸盐氮的含量进行定量分析。优化测定条件,得最佳测定条件为:氢氧化锌处理水样,1g/L碱性品红2.00mL,反应时间20min。测得水样中亚硝酸盐氮平均含量为2.875mg/L。该方法试剂无毒,操作简便快捷,干扰小,适合水质中亚硝酸盐氮的定量分析。
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.
