The　effects　of　adsorbate　concentration,　adsorbent　concentration,　temperature,　pH,　and　ion　strength　on　the　17beta-estradiol　(E2)　adsorption　process　by　anaerobic　granular　sludge　(AnGS)　were　investigated　in　this　study.　The　adsorption　process　was　analyzed　according　to　adsorption　isotherm,　adsorption　thermodynamics　and　adsorption　kinetics.　It　was　found　that　E2　was　quickly　and　effectively　adsorbed　by　AnGS.　The　adsorption　capacity　and　adsorption　removal　efficiency　of　E2　increased　as　E2　concentration　increased,　and　decreased　as　AnGS　concentration　increased.　Low　temperature,　low　pH,　and　low　ionic　strength　promoted　E2　adsorption　by　AnGS.　The　Freundlich　absorption　isotherm　accurately　described　the　E2　adsorption　equilibrium　process　by　AnGS　and　the　pseudo-second-order　model　accurately　described　the　adsorption　kinetics.　The　overall　adsorption　process　of　E2　by　AnGS　was　a　physical　adsorption　process　of　spontaneous　heat　release　controlled　both　by　film　diffusion　and　intraparticle　diffusion.
