Preliminary survey results of the content of nonylphenol polyethoxylates (NPEOs) in various household detergents sold in Taiwan are presented. This survey was conducted to elucidate the concentration of NPEOs in household detergents and support pollution prevention and control programs. The concentrations of NPEOs in detergents and cleaners were determined by HPLC with a C8 reversed-phase column and equipped with fluorescence detection. The accuracy and precision of the method was validated and was successfully applied to determine concentrations of NPEOs in household detergents. The results show that NPEOs were detected in 41% of 90 household detergents at concentrations from 0.2 to 21%. The highest concentration of NPEOs (21%) was detected in a laundry liquid especially designed for washing socks. Reversed-phase liquid chromatography connected with electrospray mass spectrometry confirmed the results.
本文呈现了台湾地区销售的各类家用洗涤剂中壬基酚聚氧乙烯醚(NPEOs)含量的初步调查结果。开展此项调查是为了阐明家用洗涤剂中NPEOs的浓度,并支持污染防治项目。采用配备荧光检测的C8反相柱通过高效液相色谱法测定洗涤剂和清洁剂中NPEOs的浓度。该方法的准确性和精密度经过验证,并成功应用于测定家用洗涤剂中NPEOs的浓度。结果显示,在90种家用洗涤剂中,41%检测出含有NPEOs,浓度范围为0.2%至21%。在一款专门用于洗袜子的洗衣液中检测到最高浓度的NPEOs(21%)。反相液相色谱与电喷雾质谱联用证实了该结果。
