Abstract : 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.
