Extraction and determination of ortho-phenyphenol in export textiles by accelerated solvent extraction technique

In order to break down the technological barrier set by the European Union,develop an accelerated solvent extraction technique for extraction and determination of ortho-phenyphenol in export textiles.According to this method,the ortho-phenyphenol in textiles was extracted with methanol,50℃,10.34 MPa,determined with HP-5 capillary column by GC-FID.The detection limit was 0.05μg/g,the linear equation wasY= 19.891X-0.599 8,r2=0.999 8,the linear range was 0.1-15.0μg/mL,and the average recovery was 100.8%.The method is simple and sensitive and suitable for detecting ortho-phenyphenol in export textiles.
