摘要
本文初步探讨了连续流动分析法测定废水中总氮的方法。通过将测量量程扩大至20mg/L,对混浊的废水进行过滤处理,实验结果表明,该方法的相关系数达0.9999,方法检出限为0.02mg/L,加标回收率在99.5%-108%之间,RSD为0.2%-0.6%,可适用于废水中总氮的分析。
This essay basically discussed how Continuous Flow Analysis （ CFA ） was used to determine the total nitrogen in waste water. The muddy water was filtered by enlarging the measuring range to 20 mg/L. Test results show that the Correlation Coefficient of this method reached to 0.9999, MDL was 0.02mg/1. The standardized recovery rate was 99.5% - 108%. RSD was 0.2% - 0.6%. This method can be used to determine the total nitrogen in waste water.
