In this study, the potential of eggplant powder was investigated to remove the methylene blue (MB) dye from an
aqueous solution by adsorption method on the surface of eggplant powder, as it is Low Cost and widely available,
the studies were conducted at several parameters such as equilibrium time, absorbed dose, initial dye
concentrations and temperatures were studied to monitor their effects on the dye adsorption process. The
optimum conditions for MB absorption on adsorbents (EP) were found as: equilibrium time (30 minutes),different
temperatures for an initial dye concentration of 24mg / L, an absorbed dose of 0.05g , The results also showed that
the increase in temperatures led to a decrease in the adsorption efficiency, and two models of adsorption
isotherms were selected, which are Langmuir and Freundlich, The results indicated the large conformity of the
Freundlich model, Thermodynamic functions were calculated for the adsorption process, including entropy,
enthalpy, and Gibbs free energy, The (?H) obtained negative value that indicated adsorption of MB dye was an
exothermic process while (?G)values were negative which indicated that adsorption of MB dye was a spontaneous
process
