摘要：

Clenbuterol　(CLE)　and　ractopamine　(RAC)　are　two　kinds　of　typical　β2-adrenergic　agonists　which　pose　a　serious　threat　to　the　health　of　human　beings.　In　this　work,　10　kinds　of　metal-organic　frameworks　(MOFs)　with　high　stability　and　various　pore　features　are　screened　to　assess　adsorption　performance　for　CLE　and　RAC.　An　Al(III)-MOF　(BUT-19)　with　abundant　ethyl　groups　exhibits　exceptional　performance　in　removing　CLE　and　RAC　from　water.　The　maximum　adsorption　capacity　for　CLE　and　RAC　are　up　to　294.1　and　366.3　mg/g　under　the　optimum　adsorption　conditions,　respectively.　Meanwhile,　the　adsorption　mechanism　effects　of　pH,　temperature,　and　coexisted　ions　are　investigated　systematically.　It　is　found　that　the　MOF　pore　size　and　weak　hydrogen-bond　interactions　between　CLE/RAC　molecules　and　the　MOF　are　the　main　causes　leading　to　the　extraordinary　adsorption.　This　study　provides　a　new　idea　for　the　purposeful　design　and　synthesis　of　MOFs　for　removing　environmental　pollutants　and　sheds　light　on　the　depuration　of　contaminated　water.
