| 摘 要： | 采用流动注射-分光光度法测定了环境水样中的氨氮。其线性范围为0～5．0mg／L；方法的检出限为0．01mg／L。通过分析两环境标准样品，对方法的精密度和准确度作了考核，所得测定结果与标准值相符，相对标准偏差（n=6）均小于2％。对方法的回收率作了试验，所得结果在94．1％～100．3％之间。

The Flow Injection--Spectrophotometry Determination of Ammonia in Water |
| |
| Abstract: | In this paper, Flow Injection--Spectrophotometry is used to determine the ammonia nitrogen contents of the environmental water samples. The linear range is 0 - 5.0mg/L and the method detection limit is 0.01 mg/L. By determining the two environmental standards,the precision and accuracy of the method are assessed. And the measurement results are certified with the values of the standards,and RSD （n = 6） is less than 2%. The recoveries of the method are 94.1%- 100.3%. |
