摘　　要：利用超声萃取-HPLC-DAD联用技术测定纺织产品中苯二酚同分异构体的含量,优化色谱参数和样品前处理条件。优化好的样品前处理条件为:室温下超声萃取,萃取溶剂为甲醇,萃取时间30 min。在优化条件下,苯二酚同分异构体在2 mg/L~30 mg/L质量浓度范围内,方法定量限(LOQ)为2.0 mg/kg,线性相关系数均达到0.99以上,加标回收率为80.13%~101.63%,相对标准偏差为3.15%~9.94%(n=7)。该方法样品前处理简单、定量限低、测定结果准确。Using ultrasonic extraction-HPLC-DAD combined technology to determine the content of isomers of hydroquinone in textile products,optimizing chromatographic parameters and sample pretreatment conditions.The optimized sample pretreatment conditions are:ultrasonic extraction at room temperature,extraction solvent is methanol,and extraction time is 30 minutes.Under optimized conditions,the isomers of hydroquinone have a mass concentration range of 2 mg/L~30 mg/L,a method limit of quantification(LOQ)of 2.0 mg/kg,linear correlation coefficients above 0.99,standard recovery rates of 80.13%~101.63%,and relative standard deviations of 3.15%~9.94%(n=7).This method has simple sample pretreatment,low quantification limit,and accurate measurement results.
