摘要
建立了测定纺织品中烷基酚(AP)和烷基酚聚氧乙烯醚(APnEO)(n=2～16)的正相高效液相色谱法。以甲醇为提取溶剂,用索氏抽提法提取纺织品中的AP和APnEO,用正相高效液相色谱法测定,并对提取溶剂、提取方式和净化条件等前处理条件进行优化。该方法的检出限为1.0mg/kg,回收率为90.4%～104.1%,相对标准偏差为0.64%～4.21%。采用该方法对多种基质纺织品进行检测,可满足残留检测要求。
A method for the simultaneous determination of alkylphenols （ AP ） and alkylphenol polyethoxylates （APnEO） （n =2 - 16） in textiles was developed by normal-phase high performance liquid chromatography （NP-HPLC）. The residues of AP and APnEO in the samples were extracted with methanol by Soxhlet extraction. The pretreatment conditions such as extraction solvents, extraction methods and clean-up methods were optimized. The sample was purified by an HLB solid-phase extraction column and separated on an amino column （250 mm × 4.6 mm, 5 μm） with hexane-isopropanol （90： 10, v/v） and isopropanol-water （90： 10, v/v） as mobile phases at a flow rate of 1.0 mL/min and determined by a fluorescence detector. AP and each APnEO oligomer were separated successfully within a reasonable time with gradient elution, which are difficult to be separated by using conventional reversed-phase high performance liquid chromatography （RP-HPLC）. The detection limit was 1.0 mg/kg for each analyte. The recoveries ranged from 90.4% to 104. 1% with the relative standard deviations （RSDs） ranged from 0.64% to 4.21%. This method is suitable for the determination of alkylphenols and alkylphenol polyethoxylates in textiles.
