This study aimed to investigate the removal of bisphenol A (BPA), a harmful environmental contaminant, using modified pine-based porous carbon (PC-1). The PC-1 was synthesized by activating pine-based porous carbon (PC) with potassium hydroxide (KOH) and reconstructing its surface with sodium borhydride (NaBH_4), which increased surface hydroxyl groups, decreased carbonyl groups, and enhanced surface functionalities, as evidenced by the increased I_D1/I_G ratio. The PC-1 exhibited a significantly improved BPA degradation efficieney compared to unmodified PC in a persulfate system. The degradation efliciency improved by 45%, 18%, and 64% at 25, 35, and 45 ℃ , respectively. Mechanistic studies revealed the involvement of both radical and non-radical pathways in BPA removal. Intrinsic carbon defects acted as active sites for persulfate activation, while oxygen-containing functional groups played a crucial role in influencing the activation pathway. This work highlights the potential of surface-modified PC-1 for efficient BPA removal, providing valuable insights into the design of advanced materials for environmental remediation.
