Volatile fatty acids (C2-C7) analysis in wool scouring water and lanolin is presented. These substances are of major interest as malodorous compounds in urban and industrial wastewaters. In this work, they have been analysed in wool scouring water by headspace solid-phase microextraction followed by gas chromatography negative chemical ionisation mass spectrometry. Most of the volatile fatty acids have been identified at microg g(-1) levels. In addition, since lanolin is a major impurity of raw wool, volatile fatty acid patterns of wool scouring water and lanolin have been compared in order to establish the origin of these compounds in the wastewater. Finally, the efficiency of the deodorization step, mandatory to obtain commercial lanolin, has been assessed taking into account the decrease in volatile fatty acid content from the raw wool to the lanolin.
本文介绍了羊毛洗涤水和羊毛脂中挥发性脂肪酸（C2 - C7）的分析。这些物质作为城市和工业废水中的恶臭化合物备受关注。在这项工作中，通过顶空固相微萃取结合气相色谱负化学电离质谱法对羊毛洗涤水中的这些物质进行了分析。大多数挥发性脂肪酸已在微克/克（-1）水平上被鉴定出来。此外，由于羊毛脂是原羊毛的主要杂质，因此对羊毛洗涤水和羊毛脂的挥发性脂肪酸模式进行了比较，以确定废水中这些化合物的来源。最后，考虑到从原羊毛到羊毛脂挥发性脂肪酸含量的降低，评估了获得商业羊毛脂所需的除臭步骤的效率。
