Abstract：

In　this　study,　poly(acrylic　acid-co-acrylamide)　(PAAAM)　hydrogels　were　used　to　remove　uranium　(VI)　ions　in　wastewater　and　characterized　by　FTIR,　SEM,　EDX.　The　effects　of　pH　value,　coexistence　of　ionic　strength,　contact　time,　initial　U　(VI)　ion　concentration　and　adsorption　temperature　were　also　studied.　Adsorption　data　fitted　well　with　pseudo-second-order,　intra-particle　diffusion　model　and　Langmuir　isotherm　mode,　the　maximum　adsorption　capacity　of　U(VI)　was　713.24 mg g−1.　Thermodynamic　analysis　shows　that　the　adsorption　of　U(VI)　is　spontaneous　endothermic.　PAAAM　hydrogel　has　excellent　regeneration　performance,　after　five　time　adsorption–desorption　cycles,　the　adsorbent　still　maintained　99.24%　adsorption　capacity.　©　2018,　Akadémiai　Kiadó,　Budapest,　Hungary.
