Characterization and Analysis of Argania spinosa Shells from Souss-Massa Area: Application in the Adsorption of Methylene Blue in Aqueous Solution

This study focused on the adsorption in aqueous solution of methylene blue (MB), a cationic dye used textile industry, by crushed Argan shells (used as raw materials) from southern region Morocco. These were first characterized different technical analyses: elemental analysis, biochemical IR spectroscopy, thermogravimetric scanning electron microscopy, mercury porosimetry, and zetametry. The kinetics was then studied varying experimental parameters such concentration solution. We note that at pH = 8 , there is an elimination up to 232.6 mg/g, during equilibrium time 180 min. correlation coefficient showed pseudosecond-order kinetic equation best describes for tested material. isotherms MB are suitably described Langmuir model which provide theoretical data. thermodynamics indicates spontaneous endothermic process. It concluded increase temperature leads greater biosorbent.
