An　investigation　was　conducted　on　the　adsorption　and　desorption　of　three　basic　amino　acids　(L-His,　L-Lys　and　L-Arg)　with　a　spherical　cellulose　adsorbent　containing　the　carboxyl　group.　Static　experiments　were　carried　out　as　function　of　pH,　initial　amino　acid　concentration,　adsorption　time　and　temperature.　The　adsorbent　showed　excellent　adsorption　capacities　for　the　mentioned　basic　amino　acids.　The　equilibrium　adsorption　data　of　the　amino　acids　on　adsorbent　were　analyzed　by　Langmuir　and　Freundlich　models.　The　kinetics　of　basic　amino　acids　adsorption　nicely　followed　the　second-order　rate　expression　which　demonstrated　that　chemical　adsorption　plays　a　significant　role　in　the　adsorption　mechanism.　Moreover,　dynamic　experiments　were　performed　to　determine　the　breakthrough　curves.　Regeneration　experiments　were　tried　four　cycles　and　the　results　implied　that　the　cellulose　adsorbents　had　such　advantages　as　simple　regeneration,　high　recovery　and　reusability.　©　2011　IEEE.
