In　this　study,　a　novel　adsorbent　of　lanthanum-modified　platanus　ball　fiber　biochar　(La-TC)　was　developed　for　efficient　adsorption　and　reuse　of　phosphate　from　actual　wastewater.　La-TC　adsorbing　phosphate　could　be　used　as　agricultural　fertilizer.　The　saturated　adsorption　capacity　of　phosphate　on　La-TC　was　148.11　mg/g　at　dosage　of　0.4　g/L,　initial　solution　pH　of　6.0,　contact　time　of　20　min,　and　temperature　of　35　degrees　C,　which　was　much　higher　than　most　phosphate　biochar　adsorbents.　Simultaneously,　La-TC　had　a　wide　pH　(3-9)　adsorption　stability,　a　strong　ability　to　resist　interference　of　anti-competitive　anion　(SO42-　and　NO3-),　and　an　outstanding　regeneration　ability.　Fourier　transform　infrared　spectroscopy　(FTIR),　and　X-ray　photoelectron　spectroscopy　(XPS)　were　used　to　reveal　the　adsorption　mechanism　of　La-TC　to　phosphate,　including　electrostatic　adsorption,　ligand　exchange,　and　complexation　mechanisms.　In　the　fixed　bed　column　experiment　of　phosphorus　removal　from　real　wastewater,　the　maximum　treated　bed　volume　was　420,　440　and　480　(BV)　under　the　bed　flow　of　1　mL/min　and　La-TC　of　0.5,　0.75　and　1.0　g,　respectively.　Outcomes　suggested　that　La-TC　had　a　broad　prospect　of　engineering　application　for　removal　and　reuse　of　phosphate　from　wastewater,　also　realizing　the　resource　utilization　of　wasted　platanus　ball.　(C)　2020　Institution　of　Chemical　Engineers.　Published　by　Elsevier　B.V.　All　rights　reserved.
