EQUILIBRIUM STUDY OF THERMODYNAMIC AND KINETIC OF ACTIVATED CARBON ENSUING FROM Azadirachta indicaBARK L ACTIVATED CARBON ACIDIC DISPERSION FOR THE REMOVAL OF METHYLENE BLUE DYE
The investigations on the removal of Methylene Blue dye from aqueous solutions by adsorbent utilising Azadirachtaindica Bark L Activated Carbon charcoal were conducted under a broad range of experimental designs andoptimisation settings. The adsorption equilibrium approach has been used to investigate each of the factors. TheLangmuir, Freundlich, and Tempkin adsorption isotherms were employed to assess the adsorption isotherm. Calculations were made for thermodynamic parameters such ∆as Ho , ∆S o and ∆Go . It illustrated howthe adsorptionwas endothermic and spontaneous. The fake second-order kinetics made much more sense than the pseudo-first- order kinetic model. FT-IR, SEM, AFM, BET, and powder XRD were used to measure it both before and after theadsorption of a substance that resembled the colour Congo red in water.
