In　this　study,　a　novel　iron　and　nitrogen　co-doped　biochar　(Fe/N-biochar)　was　successfully　prepared　and　employed　as　an　efficient　adsorbent　for　micropollutants.　The　maximum　adsorption　capacity　of　Fe/N-biochar　for　bisphenol　A　(BPA)　was　54　mg/g,　which　is　significantly　better　than　that　of　commercial　graphene　(19　mg/g)　and　activated　carbon　(6　mg/g).　Additionally,　for　eight　other　common　micropollutants　(e.g.,　phenol,　acetaminophen,　and　sulfamethoxazole),　Fe/N-biochar　also　exhibited　highly　enhanced　adsorption　performance.　The　results　of　adsorption　kinetics　and　isotherms　studies　showed　that　the　adsorption　of　micropollutants　onto　Fe/N-biochar　is　by　monolayer　coverage.　Thermodynamic　studies　further　suggested　that　the　adsorption　process　is　feasible,　spontaneous,　and　chemical　in　nature.　The　adsorption　mechanism　was　investigated　by　correlation　analysis　between　the　adsorption　capacity　and　the　physiochemical　properties　of　Fe/N-biochar.　The　results　demonstrated　that　the　strengthening　of　π–π　electron　donor-acceptor　interactions　between　the　organics　and　the　adsorbent　caused　by　the　co-doping　of　iron　and　nitrogen　was　the　dominant　driving　force　behind　the　efficient　adsorption　of　micropollutants.　Furthermore,　graphitic　N　and　Fe−Nx　were　identified　as　the　major　adsorption　sites.　Simple　heat　treatment　could　effectively　restore　the　adsorption　capacity　of　Fe/N-biochar　that　had　reached　adsorption　equilibrium.　In　view　of　its　simple　preparation　method,　highly　enhanced　adsorption　capacity,　and　excellent　recyclability,　the　prepared　Fe/N-biochar　can　be　regarded　as　a　promising　candidate　for　wastewater　treatment.　©　2021　Elsevier　B.V.
