Bisphenol A (BPA) has become prevalent in the environment due to its extensive use industrial materials, thus raising significant concerns regarding potential toxicity and health effects. In this study, an efficient eco-friendly non-thermal plasma (NTP) was used catalyze persulfate (PS) for BPA decomposition, results showed that integrated system could effectively degrade BPA. The best performance attained at a PS mass ratio of 5:1, with degradation rate 91.3% following 30 min treatment. increased increasing input voltage frequency; conversely, it decreased increase BPA’s initial concentration. Higher rates be achieved alkaline environments. Radical quenching experiments revealed SO4−•, OH•, O2−• 1O2 were important active substances involved degradation. Nine intermediate products identified by liquid chromatography–mass spectrometry (LC-MS), four pathways deduced. Additionally, analysis performed. decrease chemical oxygen demand (COD) during actual wastewater treatment suggested NTP/PS good applicability
