Abstract

Different textiles pre-processing methods including Ultrasonic Extraction method and Soxhlet Extraction method were evaluated in this study. These two pre-processing methods were used for extraction the Alkylphenol ethoxylates (APEO) from textiles. The concentration of APEO in textiles was simultaneous determinationin by High-Performance Liquid Chromatography. The precision, recovery, and repeatability of these methods were discussed. The results exhibited that the good recovery range between 85.84％ and 100.14％ was obtained during the process of the Ultrasonic Extraction. This method was validated within the concentration range at all levels. The relative standard deviation (RSD) was less than 3％ which were less enough for samples determinations of Alkylphenol Ethoxylates in textile. The Ultrasonic Extraction method to prepare samples is quicker, simpler, more stable, practical and creating smaller environmental hazards, in comparison with the Soxhlet Extraction method.

摘要

本研究评估了不同的纺织品预处理方法，包括超声波提取法和索氏提取法。这两种预处理方法用于从纺织品中提取烷基酚乙氧基化物 (APEO)。采用高效液相色谱法同时测定纺织品中APEO的浓度。讨论了这些方法的精密度、回收率和重复性。结果表明，在超声提取过程中获得了85.84％～100.14％的良好回收率。该方法在所有水平的浓度范围内都得到了验证。相对标准偏差（RSD）小于3％，不足以用于纺织品中烷基酚聚氧乙烯醚的样品测定。超声波提取方法制备样品更快，
