| dc.description.abstract | The growing demand for adsorbents used in environmental protection processes has made their price increasingly expensive, which gives rise to further research for the manufacture of new, less expensive adsorbent materials from non-conventional materials, specifically from biomass. The objective of our work is to prepare activated carbon from orange peel by carbonization, through its use in the removal of methyl orange (MO) dye. In this study, we are proposed to apply the adsorption process on activated carbon of a mixture containing methyl orange which is an acid dye. The adsorbent material chosen is an agri-food product, orange peel. Static adsorption tests allowed us to see that adsorption capacity is influenced by various parameters such as contact time, initial concentration and mass.the study of the isotherm shows that the Freundlich model describes well the process of adsorption of OM on orange peel. The adsorption kinetics of orange methyl on activated orange peel is perfectly described by the pseudo-first-order kinetic model. | |
