However, the activation efficiency of peroxymonosulfate (PMS) or peroxydisulfate (PDS) usage and the reaction mechanism remain insufficiently understood. In this study, the effects of PMS/PDS dosage on the degradation of bisphenol A (BPA, 10&amp;nbsp;mg/L) were evaluated using N-doped biochar (N-BC, 0.2&amp;nbsp;g/L) assisted PS-AOPs. The reaction pathways were comprehensively investigated through a combination of characterization techniques and molecular simulations. With low PS dosages (0.05 and 0.1&amp;nbsp;mM), the degradation rate constants () were higher in N-BC/PDS (0.04 and 0.07 min−1) compared to N-BC/PMS (0.02 and 0.04&amp;nbsp;min−1), likely due to higher PDS utilization, which enhanced the contribution of the non-radical pathway. Interestingly, with higher PS dosages (0.5 and 1.5&amp;nbsp;mM), the&amp;nbsp;&amp;nbsp;values were 0.16&amp;nbsp;min−1&amp;nbsp;and 0.18&amp;nbsp;min−1&amp;nbsp;in N-BC/PMS, respectively, significantly exceeding those determined in N-BC/PDS (0.11 and 0.11&amp;nbsp;min−1). This result stemmed from the greater adsorption capacity of N-BC for PMS compared to PDS, leading to increased formation of&amp;nbsp;1O2. The contribution of non-radical pathways for both PMS and PDS increased with higher PS dosage. The results highlighted that BPA degradation improved significantly with the increase in PMS dosage; meanwhile, BPA degradation was insensitive to PDS dosage. The optimal PMS dosage for BPA degradation was found to be 1.5&amp;nbsp;mM and 0.1&amp;nbsp;mM for PDS. This study offered valuable insights for optimizing PS-AOPs in environmental remediation, helping to guide the selection of appropriate oxidants and dosages for maximizing pollutant removal.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record></records></xml>
