Established the analysis methods of drometrizole in textiles,Acetonitrile was used as the extraction solvent,and ultrasonic extraction was used to extract drometrizole from textiles.Optimized instrument analysis conditions.The results indicate that the linear range of the method is 10～50 μg/mL,the detection limits of the method are 21.2 mg/kg,the recoveries range from 94.1％to 97.4％,and the relative standard deviation is at the range of 3.4％to 5.9％.This method is easy to operate and fast to analyze and is suitable for the detection of drometrizole in textiles.
