The removal of methylene Blue (MB) in aqueous solution by the adsorption technique onto date palm fibers (DPF) as agricultural waste material was studied. Results obtained indicate that the removal efficiency of Methylene Blue varies from 93.8 to 98.5% by rising the temperature from 30 to 60°C at pH from 6 to 8. The results fit the Langmuir model for adsorption of MB on DPF. A comparison of kinetic models (pseudo first-order and the pseudo second-order) at different conditions showed that the pseudo second-order kinetic model correlate the experimental data well. Van’t Hoff equation was used to evaluate the thermodynamic parameters (ΔH, ΔS, and ΔG), which indicate that adsorption process is endothermic in nature.
