中文摘要:建
立了同时测定皮革中邻苯基苯酚和7种含氯苯酚的GC-MS联用分析方法。采用甲醇为溶剂，超声萃取皮革中的苯酚类物质，蒸发浓缩后，用乙酸酐乙酰化，正己
烷萃取，经浓缩和定容后，用GC-MS测定，外标法定量。结果表明，目标物质在0.02~0.30 mg/L范围内的线性关系良好，相关系数为0.998
9~0.999 9，平均回收率为89%~106%，相对标准偏差(n=7)为1.8%~8.8%；方法的定量下限低于0.01
mg/L。方法简便、高效、准确、灵敏，可满足进出口皮革和皮革制品中多种苯酚类物质的检测需求。

Simultaneous Determination of 2-Hydroxybiphenyl and 7 Chlorophenols in Leathers by GC-MS Method

Abstract:A
GC-MS method was developed for the simultaneous determination of
2-hydroxybiphenyl and 7 chlorophenols in leathers.The crushed leather
sample was extracted with methanol in ultrasonic bath,then evaporated
and concentrated,and then acetylated with acetic anhydride and extracted
with n-hexane.After concentrated and set the volume,the target
compounds were analyzed by GC-MS and quantified by the external
method.The results indicated that the calibration curves were linear in
the range of 0.02-0.30 mg/L,with correlation coefficients of 0.998
9-0.999 9.The mean recoveries of 2-hydroxybiphenyl and 7 chlorophenols
in the blank sample were in the range of 89%-106%，with relative standard
deviations(RSDs,n=7) of 1.8%-8.8%.The quantitation limit of the method
was lower than 0.01 mg/L.The method was simple,efficient,accurate and
sensitive,and could meet the needs of a variety of phenols substances
detection in the import and export of leather and leather products.
