The　potential　of　spherical　lignin　beads　as　an　adsorbent　to　take　up　Llysine　from　aqueous　solution　was　investigated.　The　kinetic　data　were　estimated　by　the　pseudo-first-order　and　pseudo-second-order　models.　The　mechanism　of　adsorption　was　also　studied　using　the　Boyd　model　and　Webber＇s　intraparticle　diffusion　model.　The　equilibrium　data　were　modeled　by　the　Langmuir,　Freundlich,　and　Dubinin-Radushkevich　(D-R)　isotherms　as　well.　Results　suggested　that　the　adsorption　kinetics　can　be　best　described　by　the　pseudo-first-order　model.　The　adsorption　process　initially　was　controlled　by　film　diffusion,　whereas　the　subsequent　stage　was　controlled　by　intraparticle　diffusion.　The　equilibrium　data　could　be　well　fitted　using　the　Langmuir　isotherm　model　with　a　maximum　adsorption　capacity　of　67.11　mg.g-1.　The　adsorption　characteristics　of　the　spherical　lignin　adsorbent　proved　the　feasibility　of　its　use　as　an　alternative　adsorbent　for　the　removal　of　L-lysine　from　aqueous　solution.
