Abstract
The present work consists in studying the kinetic, isothermal and thermodynamic properties related to the adsorption of Methylene Blue in industrial waters. The study proposes an package to study the adsorption on the side calculating the parameters: (Langmuir constant KL, Frendlich constant KF, the rate constants for a first order K1, pseudo-second order K2 and second order kinetic K3, and paramètres thermodynamiques) and plotting the trends, through a user-friendly graphical interface. This package aims to save time and avoid errors that may occur when processing experimental results. The experimental study of methylene blue adsorption on Argan shells was performed to verify the performance of this package. The experimental study of the adsorption of methylene blue on the shells of Argan was carried out to verify the performance of this set. It is found that the amount of adsorption of methylene blue on the shells of Argan is 90.96 mg / g for an estimated equilibrium time of 240 min. The correlation coefficient showed that the pseudo-second order kinetic equation best describes the adsorption kinetics. The experimental equilibrium data were analyzed, the Langmuir isotherm provided the best correlation. In addition, the determination of the thermodynamic parameters shows that the reaction is spontaneous and exothermic.
