| 摘 要： | 挥发性脂肪酸(VFA)是厌氧消化过程的重要中间产物,在反应器运行中,出水VFA用作重要的控制指标。通过色谱条件探索将各种脂肪酸分离,同时研究了水样酸碱度,吸附等对测定的影响,进一步优化了废水中挥发性脂肪酸的测定。方法的检出限在0.99~1.77 mg/L,回收率在90.9%~102.7%之间,相对标准差(n=5)在1.3%~3.8%之间。

| Abstract: | VFA is an important intermediate material in anaerobic digestion. VFA is a major index during the process. Separating the fatty acid by chromatographic conditions, and studying how the water＇s PH, andadsorption influnce the tests, it optimizes the test. Detection limits found were in the range of 0.99-1.77 mg·L-1. Values of recovery found were ranged form 90.9%-102.7%,RSD＇s（n=5） range form 1.3% -3.8%. |
