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.
