Adsorption of Methylene Blue (MB) from Aqueous Solution Using Mixed Sorbents Prepared from Date Pit and Olive Stone

Full Text PDF


The present study focuses on the recovery of the mixed waste food « the date pits and olive stones» in the field of industrial liquid effluent treatment.The materials was mixed and used in their native form to improve their adsorptive capacity. A rang of physicochemical analysis was performed, for the characterization of adsorbents used, among them: FTIR spectroscopy. In order to test the performances of these adsorbents we are interested in cationic dye the methylene blue considered as pollutant. The effects of several parameters such as contact times, initial concentration of dye, solution pH, and temperature and the proportion of date pits and olive stones in the mixture, were studied in batch system. The result showed that the contact time for removal of all the dyes is about ten minutes, for different concentration of the solution studied colour. For a pH range that varies between 3 and 10, it was found that a large percentage removal of dye was found for pH values above 4. Modelling of experimental results was performed using models of Langmuir and Freundlich isotherms, which show that adsorption follows the Langmuir model with high correlation coefficients.
