HPLC法测定纺织品中AP和APEO

 为了打破欧盟的技术壁垒,保障我国纺织品的顺利出口,建立了一个可同时测定纺织品中残留烷基酚和烷基酚聚氧乙烯醚的高效液相色谱测定方法。该方法以甲醇为提取溶剂,采用索氏抽提法提取纺织品中残留的辛基酚、壬基酚、辛基酚聚氧乙烯醚和壬基酚聚氧乙烯醚,采用高效液相色谱法进行测定,并对色谱条件和前处理条件进行了优化。该方法的检测限(S/N=5)分别为0.010 mg/L(OP)、0.020 mg/L(NP,OPEO)和0.050 mg/L(NPEO),回收率为96.82%~103.39%,精密度实验的相对标准偏差为1.04%~5.48%。结果表明,采用该方法对部分出口欧盟的纺织品进行检验,可满足检测工作的需要。

Determination of alkylphenol (AP) and alkylphenol polyethoxylates (APEO) in textiles by HPLC

In order to break down the technological barrier set by the European Union and to ensure the export of textile products,a simple and rapid HPLC method was described for the simultaneous determination of the residues of AP and APEO in textiles.The residues of octylphenol(OP),nonylphenol(NP),octylphenol polyethoxylates(OPEO) and nonylphenol polyethoxylates(NPEO) in the samples were extracted with methanol by Soxhlet extraction.The chromatographic separation conditions and the pretreatment conditions were optimized.The detection limit was(0.010 mg/L) for OP,(0.020 mg/L) for NP and OPEO,and(0.050 mg/L) for NPEO at(S/N=5.) The recovery ranged from 96.82% to 103.39% while the RSD was ranging from 1.04% to 5.48%.This method is applied in the analysis of some textiles exported to the European Union and the results demonstrates that this method can fully satisfy the demand of the analysis of textiles for export.
