Background: usethebentonite ,narang leaves and corn seeds as adsorbent surface for the removal of one of dyes from wastewater was studied. Objective: The adsorption of methylene blue from aqueous solution are investigate on three adsorbents Method : UV- Spectrophotometric technique to obtained the quantities of adsorption data at Different of temperatures (37 , 32 ᵒc) and at pH=1.2in an attempt to simulate the acidity of gastric fluid. Results: The quantities adsorbed of methylene blue on bentonite ,narang leaves and corn seeds were increased at 37 cᵒ.Adsorption characteristics were described using frundlich isotherm. Conclusion: The adsorption process has been foundthe value of ΔGᵒshowed the spontaneous nature of adsorption for three adsorbents and endothermic in nature and thermodynamicParameters, Gibb’s free energy (ΔG◦), change in enthalpy (ΔH◦) and change in Entropy (ΔS◦) have been calculated.
