In this study, the adsorption of malachite green (MG) onto date palm fibers (DPF) was examined in aqueous solutions. The Langmuir and Freundlich adsorption isotherm models were employed to describe the equilibrium adsorption data. The Freundlich isotherm model was found to fit the adsorption data The removal percentage of MG dye from aqueous solutions via adsorption  onto DPF adsorbent varied with pH and temperature, showing that these factors play a key role in the adsorption process. The removal percentage was found to increase with decrease in the solution temperature and in alkalinemedia. The adsorption kinetic data were fitted with a pseudo-second-order model.
