Adsorption　of　zearalenone　(ZEA)　by　hydroxyl-Fe　intercalated　montmorillonite　(OH/Fe-Mont)　was　investigated,　at　the　same　time,　the　adsorption　materials　were　analyzed　by　XRD　and　FT-IR　instrument.　Main　conclusions　of　this　work　were　drawn　as　follows:　(1)　The　adsorption　capacity　of　OH/Fe-Mont　to　ZEA　was　much　higher　than　that　of　K10-Mont.　When　the　molar　ratio　of　OH/Fe　was　1.5,　the　adsorption　capacity　of　OH/Fe-Mont　to　ZEA　reaches　the　maximum　(0.283　mg/g),　which　was　5　times　of　that　of　the　K10-Mont(0.054　mg/g).　The　result　of　XRD　analysis　shows　that　the　d001　of　hydroxyl-Fe　intercalated　montmorillonite　increased　after　modification.　The　increment　of　interlayer　space　of　montmorillonite　made　the　adsorption　amount　increase.　(2)　Freundlich　model　could　well　fit　the　adsorption　isotherms　of　zearalenone　by　both　OH/Fe-Mont　and　K10-Mont.　FT-IR　analysis　shows　that　cationic　exchange　was　the　dominant　mechanism　for　ZEA　entering　montmorillonite　interlayer.　(3)　For　sorption　of　Zearalenone　by　both　OH/Fe-Mont　and　K10-Mont,　the　optimum　adsorption　conditions　of　pH　was　8,　the　optimum　temperature　was　35℃.　(4)　A　pseudo-second-order　kinetic　model　could　well　fit　the　data,　the　correlation　coefficient　(R2)　of　two　adsorbents　were　more　than　0.99.　Both　initial　rate　and　equilibrium　adsorption　amount　of　1.5OH/Fe-Mont　were　higher　than　the　K10-Mont.　©　2016,　Chongqing　Functional　Materials　Periodical　Press　Co.　Ltd.　All　right　reserved.
