In the present research work Saw palmetto spent (SPS) was used to remove Methylene blue (MB) from aqueous solution economically. SEM and FTIR Studies were made to understand the Morphological properties of the adsorbent. Various parameters of adsorption such as, initial dye concentration, contact time, pH and temperature were studied. Langmuir, Freundlich and Temkin isotherm models were used to explain the adsorption behaviour. Pseudo-first order, pseudo-second order kinetic models and Intra-particle diffusion model were used to study adsorption kinetics. The maximum adsorption capacity value (qm = 90.9 mg g−1) for Langmuir isotherm was near to the experimental value (qm = 71.00 mg g−1). Thermodynamics of adsorption was studied and the values obtained indicate that the process is endothermic and spontaneous. It is confirmed that, SPS is an efficient adsorbent for removal of MB from aqueous solution.
