Modeling Of Adsorption Isotherms Of Methylene Blue By Olive ‎stones

Authors : Abed F . Babakhouya N . Boughrara S .


The present study focuses on the recovery of the waste food « the ‎olive stones » in the field of industrial liquid effluent treatment. The ‎material is used in its native form. In order to test the ‎performances of the adsorbent we were interested in cationic dye ‎the methylene blue considered as pollutant. The effects of several ‎parameters such as contact times, initial concentration of dye, ‎solution and pH were studied in batch system.‎ Modeling of experimental results was performed using models of ‎Langmuir and Freundlich isotherms, which show that adsorption ‎follows the Langmuir model with high correlation coefficients.‎
