Research on the detection method of isomers of hydroquinone in textile products
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 quan-tification(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.
