摘要
建立了红外光谱法直接测定ＤＴＹ油剂中脂肪酸聚乙二醇酯含量的分析方法。该方法消除了共存物聚氧乙烯非离子型表面活性剂的干扰，脂肪酸聚乙二醇的回收率为９７．５％～９８．７％，标准偏差为０．０１８％。
A method was established for the direct determination of fatty acid polyglycol ester in DTY finish by infrared spectrometry. The interference of polyoxyethylene nonionic surfactants in finish was eliminated by this method. The recovery ranged from 97 5%～98 7% and the standard deviation was 0 018%.
