采用连续流动化学分析仪(Continuous Flow Analyzer,CFA),对泥炭中的全氮进行分析。方法有良好的线性关系(r=0.9999),回收率为99%—105%,测试速度是比色法测试速度的15—20倍,操作简便、准确度好,对氮化学研究有一定意义。
Total nitrogen in peat was analyzed using Continuous Flow Analyzer (CFA). The method has a good linear relationship (r = 0.9999) and the recovery rate is 99% -105%. The test speed is 15-20 times of the colorimetric test speed. The method is simple and convenient to operate and has good accuracy. It is of certain significance to nitrogen chemistry research.
