Determination of Bisphenol A,Bisphenol F and Bisphenol S in Leather by HPLC
An analytical method for the determination of bisphenol A,bisphenol F and bisphenol S in leather was established.Leather samples were extracted by methanol ultrasound,concentrated by rotary evaporator,analyzed by HPLC at 277 nm wavelength,detected by diode array,eluted by methanol-water solution,and quantified by external standard method.The results showed that the linear correlation coefficients of bisphenol A,bisphenol F and bisphenol S in the range of 1 mg·L-1～30 mg·L-1 were greater than 0.9995,the detection limits were less than 0.64 mg·kg-1,the recovery rates of spiked standard at high,middle and low levels were 85.8%～97.1%,and the relative standard deviations were 0.11%～2.22%,which met the detection requirements.
