The　impacts　of　structure　and　morphology　of　titanate　nanomaterials　(TNs)　synthesized　by　simple　hydrothermal　method　on　the　lead　(Pb2+)　adsorption　in　aqueous　solutions　were　systematically　evaluated　and　clarified.　The　physical-chemical　properties　of　the　TNs　including　chemical　composition,　morphology,　surface　area,　and　structure　were　characterized.　The　adsorption　capacity,　kinetics,　equilibrium　model,　and　mechanism　of　as-prepared　TNs　were　investigated.　The　results　showed　that　the　structure　and　morphology　of　TNs　change　with　the　reaction　temperature　and　reaction　time.　The　flaky　structure　of　TNs　was　formed　at　100°C　and　130°C　with　reaction　time　of　24　h,　or　12–36　h　under　the　temperature　of　130°C.　Under　150°C　and　180°C　with　24　h,　48　h,　or　more　with　temperature　of　130°C,　the　synthesized　structure　was　linear.　The　flakes　structure　of　TNs　had　higher　adsorption　capacity　for　Pb2+　than　linear　structure.　The　adsorption　capacity　on　Pb2+　was　up　to　504.12　mg/g,　and　the　adsorption　kinetics　for　Pb2+　followed　pseudo-second-order　model.　The　equilibrium　data　were　in　accordance　with　Langmuir　model.　The　adsorption　of　heavy　metals　by　flaky　TNs　could　be　attributed　to　the　interaction　of　heavy　metal　ions　with　hydroxyl　groups　in　TNs.　This　study　has　shown　that　titanate　nanosheets　could　be　a　potential　adsorbent　for　the　removal　of　Pb2+　from　aqueous　solution.　©　2018　Desalination　Publications.　All　rights　reserved.
