摘要

采用特制毛细管柱，研究了猪舍废弃物和污泥在pH 5.0 ~ 5.5厌氧降解过程中游离脂肪酸谱的变化。腐烂前主要成分为游离脂肪酸，碳原子为18 ~ 22个。随着发酵时间的延长，高等酸形成的短链酸所占的比例增加。

Gas chromatographic analysis of free fatty acids. Part 2: Determination of free fatty acids during anaerobic putrefaction

By using tailor-made capillary columns the changes of the free fatty acid spectrum during anaerobic putrefaction of piggery waste and sludge at pH 5.0–5.5 were examined. Free fatty acids with 18 to 22 carbon atoms were the main components before putrefaction. With progressive fermentation time the share of short chain acids formed from higher acids was increased.
