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.
