As　typical　pharmaceuticals　and　personal　care　products　(PPCPs),　metronidazole　(MNZ)　and　bisphenol　A　(BPA)　normally　presented　in　sewage　effluent　and　surface　water.　The　nitrogen-doped　multi-walled　carbon　nanotube　(NCNT)　membrane　was　prepared　and　utilized　as　a　peroxymonosulphate　(PMS)　catalyst　to　degrade　MNZ　and　BPA.　Within　the　NCNT　membrane/PMS　catalytic　system,　MNZ　and　BPA　can　be　efficiently　degraded,　while　different　catalytic　degradation　mechanism　exists　related　with　their　structure,　adsorption　properties　and　even　PMS　dosage.　The　optimal　conditions　for　the　degradation　of　MNZ　and　BPA　were　investigated.　Quenching　tests　and　electron　paramagnetic　resonance　examination　demonstrated　that　•OH　radicals　and　1O2　played　roles　in　MNZ　degradation,　while　surface-bound　radicals　and　1O2　dominated　BPA　degradation　within　the　NCNT　membrane　catalytic　PMS　system.　Electrochemical　tests　proved　that　an　electron-transfer　process　between　NCNT　membrane　and　PMS　during　MNZ　degradation,　and　the　electron-transfer　process　was　further　verified　with　the　degradation　experiment　in　the　binary-solute　system　(BPA　and　MNZ).　PMS　dosage　had　little　influence　on　the　degradation　mechanism　of　MNZ　and　BPA.　©　2024　The　Authors
