This　study　evaluated　the　potential　application　of　a　biomass　material,　corncob　lignocellulose　(CL),　as　a　novel　adsorbent　for　the　removal　of　basic　dyes　from　aqueous　solutions.　The　adsorption　behavior　and　mechanism　of　basic　dyes　on　CL　was　investigated　via　batch　experiments.　Both　adsorption　and　desorption　studies　showed　that　the　attachment　of　basic　dyes　onto　CL　was　ascribed　to　a　combined　interaction　involving　electrostatic　attraction　and　chemisorption.　The　decolorization　efficiency　of　CL　increased　with　increasing　solution　pH　and　temperature.　Thermodynamic　parameters　demonstrated　the　spontaneous　and　endothermic　nature　of　the　adsorption.　The　dye　uptake　process　was　best　described　by　the　Langmuir　isotherm.　The　adsorption　capacity　of　CL　for　Methylene　blue,　Crystal　Violet　and　Malachite　Green　at　30°C　was　calculated　to　be　145.8,　121.8　and　65.7　mg/g,　respectively.　©　(2011)　Trans　Tech　Publications.
