In　this　study,　the　removal　of　hexavalent　chromium,　a　nonradioactive　analogue　of　pertechnetate,　from　aqueous　solution　by　bamboo　shoot　shell　(BSS)　biosorbent　was　investigated.　Characterization　of　the　sorbent　was　performed　by　element　analysis　and　Fourier　transform　infrared　spectroscopy.　The　effects　of　diverse　parameters　including　solution　pH,　adsorbent　concentration　and　adsorption　time　on　the　adsorption　process　were　discussed　in　detail.　The　adsorption　of　Cr(VI)　by　the　BSS　obeyed　Elovich　kinetic　model　and　Freundlich　isotherm　model.　The　maximum　adsorption　capacity　based　on　Langmuir　model　for　BSS　was　28.72 mg/g,　which　was　higher　than　that　of　other　biosorbents　previously　reported　in　the　literature.　The　thermodynamic　analysis　suggested　that　Cr(VI)　adsorption　was　a　spontaneous　endothermic　process.　On　the　basis　of　these　results,　an　adsorption-reduction　interaction　on　the　heterogeneous　surface　of　biosorbent　would　be　the　predominant　mechanism.　The　findings　herein　revealed　that　the　BSS　had　great　potential　as　a　suitable　and　sustainable　biosorbent　material　for　the　removal　of　pertechnetate.　©　2019,　Akadémiai　Kiadó,　Budapest,　Hungary.
