Plastic　pollution　has　become　one　of　the　most　pressing　environmental　issues.　Meanwhile,　developing　highly　efficient　adsorbents　for　uranium　removal　from　the　wastewater　of　its　tailings　is　also　of　great　significance　in　environmental　protection.　In　this　study,　wastes　of　the　plastic　membrane　in　daily　life　were　recycled　and　functionalized　to　treat　uranium　pollution　in　the　environment.　Membrane　adsorbent　with　amidoxime　(AO)　group　was　successfully　prepared　using　recycled　plastic　membranes　through　two-step　polymerization.　A　network　of　nano　holes　and　nanostructured　particles　were　observed　on　the　surface　of　the　AO　modified　membrane　(AO　-membrane)　adsorbent.　The　adsorption　performances　from　uranium　solution　and　uranium　tailings　wastewater　were　evaluated　in　batch　and　column　adsorption　experiments.　AO-membrane　exhibited　good　removal　performance　in　a　wide　pH　range　from　2　to　8.　After　adsorption　in　uranium　tailings　wastewater,　the　equilibrium　concentrations　of　uranium　in　solution　were　lower　than　50　mu　g/L,　meeting　the　national　standard　of　uranium　solution　discharge　(50　mu　g/L).　AO-membrane　could　reach　adsorption　equilibrium　within　5　h　in　uranium　tailings　wastewater　and　present　uranium　removal　ratio　of　nearly　100%.　These　indicated　that　this　AO-membrane　could　be　used　for　deep　purification　of　wastewater,　especially　with　low　uranium　concentration.　AO-membrane　exhibited　a　remarkable　reuse　performance　and　long　service　life.　During　the　10　cycles　of　adsorption　and　desorption,　AO-membrane　exhibited　almost　100%　uranium　removal　ratio　even　after　ten　adsorption　and　desorption　cycles.　This　work　provides　new　insights　into　the　technology　of　waste　control　by　waste.
