Bisphenol A (BPA) is an endocrine disruptor and is toxic at low concentrations. Furthermore, in order to oxidize BPA at the water treatment, an economical treatment method is required. This study was the first study to apply hydrodynamic cavitation/persulfate (HC/PS) processes to degrade BPA and investigated the effects of important operating parameters, such as HC inlet pressure, PS loading, pH, temperature and other anions. The results showed that the optimal pressure of HC was 0.5 MPa and the rate constant increased as the PS load concentration increased. The contribution of OH and SO₄⁻ to BPA oxidation using HC/PS processes was 10.3% and 89.7%, respectively. The reaction rate constant decreased with increasing pH and the reaction rate constant increased with increasing temperature. The activation energy was 69.62 kJ mol⁻¹. The effects of other anions on BPA degradation were in the following order: Cl⁻> NO₃⁻> HCO₃⁻. Five major intermediates were formed in the HC/PS processes and they were obtained during 120 min of operation. Based on this, this study described the decomposition pathway of BPA. The kinetic study and economic evaluation of the HC/PS processes can be used as basic data for the real wastewater treatment process in the future.

双酚A（BPA）是一种内分泌干扰物，在低浓度下有毒。此外，为了在水处理中氧化BPA，需要经济的处理方法。这项研究是第一个应用水力空化/过硫酸盐（HC / PS）工艺降解BPA的研究，并研究了重要操作参数的影响，例如HC入口压力，PS负载，pH，温度和其他阴离子。结果表明，HC的最佳压力为0.5 MPa，速率常数随PS负荷浓度的增加而增加。OH和SO ₄的贡献^-使用HC / PS工艺对BPA的氧化反应分别为10.3％和89.7％。反应速率常数随pH值升高而降低，反应速率常数随温度升高而升高。活化能为69.62kJ mol ^-1。其它阴离子对BPA降解效果都按以下顺序：氯^- > NO ₃ ^- > HCO ₃ ^- 。在HC / PS工艺中形成了五种主要中间体，它们是在120分钟的运行过程中获得的。在此基础上，本研究描述了双酚A的分解途径。HC / PS工艺的动力学研究和经济评估可以用作将来实际废水处理工艺的基本数据。
