摘 要:建立了气相色谱-质谱(GC—Ms)测定纺织品中16种含氯酚及邻苯基苯酚、β-萘酚残留量的方法。样品经甲醇超声提取、浓缩后,用0.1mol/L硼砂溶液溶解,再经乙酸酐乙酰化后正己烷提取,用GC—MS测定,内标法定量。在0.025—1.0mg/L范围内,方法的线性关系良好,相关系数为0.9993—0.9999,添加回收率为83%-112%,相对标准偏差为0.26%-8.82%。该方法简便、快速、灵敏度高,完全可满足进出口纺织品中16种含氯酚及邻苯基苯酚、β-萘酚残留量检测的要求。A GC -MS method was developed for the determination of 16 chlorophenols, o-phenyphenol and β-naphthol in textiles. The sample was extracted with methanol in ultrasonic bath. The extract was concentrated and redissolved in 0. 1 mol/L borax solution, then was derivatized by acetic anhydride and extracted by hexane. The target of compounds were analyzed by GC - MS with internal standard method. The result indicated that the calibration curves showed good linear relationships between the peak area and concentration in the range of 0. 05 - 1.0 mg/L for o-phenyphenol(OPP) and ,β-naphthol( B - N), and 0. 025 - 1.0 mg/L for the rest of analytes. The correlation coefficients were in the range of 0. 999 3 -0. 999 9. The average recoveries of 16 chlorophenols, o-phenyphenol and β-naphthol from the eontton sample spiked at three concentration levels of 0. 05, 0. 1,0. 5 mg/kg ranged from 83% to 112% with relative standard deviations of 0. 26% - 8.82% . The method was simple, rapid and sensitive, and was suitable for the determination of 16 chlorophenols, o-pheny- phenol and β-naphthol in the import and export of textiles.
