Objective: To establish a method for determination of P-cresol and Bisphenol A in drinking water by UPLC. Methods: The samples were pre-treated with SPE and eluted by methanol through HLB column. It was determined by UPLC ,quantified with fluorescence detector ,performed on a WATERS ACQUITY UPLC BEH C181.0×50mm column, acetonitrile and Ammonium acetate were used as mobile phase. Results: The detection limits for P-cresol and Bisphenol A were 0.003ug/mL and 0.005ug/mL. In the linear ranges, correlation coefficients were both above 0.999 and the precision were less than 5%. The mean recoveries were between 96.5% and 106.0%. Conclusion: The method is simple, fast , sensitive, precisive and accurate. It’s the ideal way to P-cresol and Bisphenol A for the determination of drinking water.
