Hydroquinone　(HQ)　in　wastewater　is　of　great　concern,　as　it　is　harmful　to　human　health　and　threatens　the　ecological　environment.　However,　the　existing　adsorbents　have　low　adsorption　capacity　for　HQ.　To　improve　the　removal　of　HQ,　N,S-codoped　activated　carbon-ZIF-67　(NSAC-ZIF-67@C)　was　synthesized　in　this　study　by　in　situ　growth　of　ZIF-67　on　N,S-codoped　activated　carbon　(NSAC)　and　carbonization.　The　influence　of　pH,　contact　time,　and　initial　concentration　on　the　adsorption　behaviors　of　NSAC-ZIF-67@C　on　HQ　were　investigated.　Owing　to　the　synergistic　effect　of　abundant　active　sites　and　well-developed　pore　structure,　the　NSAC-ZIF-67@C　achieved　a　prominent　adsorption　capacity　of　962　mg·g-1　and　can　still　retain　high　adsorption　performance　after　5　cycles　for　HQ,　which　is　superior　to　that　of　reported　other　adsorbents.　HQ　adsorption　follows　the　pseudo-second-order　kinetics　model　(R2　=　0.99999)　and　the　Freundlich　isotherm　model.　X-ray　photoelectron　spectroscopy　(XPS)　analysis　before　and　after　adsorption　as　well　as　density　functional　theory　(DFT)　calculation　results　showed　that　pyridinic-N-termini　were　conducive　to　the　π-π　interactions　and　hydrogen-bonding　interactions.　Therefore,　the　adsorption　mechanisms　of　NSAC-ZIF-67@C　on　HQ　involve　pore　filling,　electrostatic　attraction,　π-π　interaction,　and　hydrogen　bonding.　This　study　is　expected　to　provide　a　reference　for　designing　highly　effective　adsorbents　for　wastewater　treatment.　©　2024　American　Chemical　Society.
