A　new　nanostructured　amino-functionalized　magnetic　bacterial　cellulose/activated　carbon　(BC/AC)　composite　bioadsorbent　(AMBCAC)　was　prepared　for　removal　of　Pb2+　and　methyl　orange　(MO)　from　aqueous　solution.　The　results　demonstrated　that　the　equilibrium　adsorption　capacity　(qe)　for　Pb2+　obviously　increases　by　2.14　times　after　introduction　of　amino　groups,　the　optimum　pH　for　Pb2+　and　MO　adsorption　was　5.0　and　3.0,　respectively,　and　the　qe　of　AMBCAC　was　161.78　mg　g−1　for　Pb2+　and　83.26　mg　g−1　for　MO　under　the　optimal　conditions　in　this　investigation.　The　kinetics　and　adsorption　isotherm　data　of　the　sorption　process　were　well　fitted　by　pseudo-second-order　kinetic　model　and　Langmuir　isotherm　respectively.　The　thermodynamic　results　(the　Gibbs　free　energy　change　ΔG　<　0,　the　enthalpy　change　ΔH　>　0,　the　entropy　change　ΔS　>　0)　implied　that　the　adsorption　process　of　Pb2+　and　MO　was　feasible,　endothermic　and　spontaneous　in　nature.　These　results　support　that　the　AMBCAC　composite　developed　in　this　work　can　provide　a　cheap　and　efficient　way　for　easy　removal　of　both　Pb2+　and　MO　as　a　promising　adsorbent　candidate　for　wastewater　treatment.　©　2017
