 Abstract: Method of determining bisphenol A in PVC food contact plastic, the sample was ultrasonic extraction with tetrahydrofuran, purification with C18 solid phase extraction column, sample detection of bisphenol A by high performance liquid chromatography. The results show that: bisphenol A in the concentration range of 02-10 μg·mL-1 have a good linear relationship (R2=0999 9), the method detection limit (S/N=3) for 032 mg·kg-1, the average recovery rate was 900%-950%. This method is rapid, simple, reliable, and can be used for analysis and detection of bisphenol A in PVC food contact plastic.

 Key words: bisphenol A;solidphase extraction; high performance liquid chromatography; food contact plastic
