摘要:

建立了中空纤维液相微萃取-高效液相色谱法测定纺织品中10种含氯苯酚类化合物的方法。系统地优化了影响萃取效率的因素,得到的最佳萃取条件为:萃取溶剂为正己烷,接受相NaOH溶液的浓度为0.10 mol/L,萃取时间为60 min,搅拌速度为600 r/min。在最佳萃取条件下,10种含氯苯酚在0.01~1.00 mg/L范围内线性关系良好(r>0.999),10种含氯苯酚的检出限(信噪比为3)为0.01 mg/kg,富集倍数为95~101。在空白样品中添加0.01、0.05和0.1 mg/kg 3个不同水平的10种含氯苯酚类化合物,其平均回收率为78.8%~105.1%,相对标准偏差为0.3%~7.3%。研究结果表明该方法灵敏度高、简便、准确,可用于纺织品中含氯苯酚类化合物的测定。

Abstract:

A method was investigated for the determination of 10 chlorinated phenols in textiles by hollow fiber liquid phase micro-extraction (HF-LPME) coupled with high performance liquid chromatography (HPLC). The experimental conditions of hollow fiber liquid-phase micro-extraction were optimized, such as the nature of organic solvent, the concentration of acceptor phase, stirring rate, extraction time. The optimum extraction conditions were as follows: hexane was used as the organic solvent; the concentration of NaOH solution as acceptor phase was 0.10 mol/L; the stirring rate was 600 r/min; and the extraction time was 60 min. Under the optimal conditions, the calibration curves of the 10 chlorinated phenols were obtained in the range of 0.01-1.00 mg/L (r>0.999); the limits of detection (S/N=3) of the chlorinated phenols were 0.01 mg/kg; and the enrichment factors were 95-101. The proposed method was applied for the determination of the 10 chlorinated phenols in real textile samples. The average recoveries were in the range of 78.8%-105.1% at the spiked levels of 0.01, 0.05 and 0.1 mg/kg; and the relative standard deviations (RSDs) were in the range of 0.3%-7.3%. This method is sensitive, simple, accurate and suitable for the determination of chlorinated phenols in textile samples.
