Abstract: The adsorption properties of methylene blue dye, Bismarck brown Y dye, and Indigo dye on Cedrus libani (Elizabeth leaf) was investigated as a function of contact time, initial dye concentration, biomass dose, pH, dissolved salts, biomass particle size and temperature. This work is aimed at expanding the field of application of natural biomass for the treatment of dye waste effluents. The biomass was characterized by scanning electron microscopy (SEM), as well as Fourier Transformed Infrared Spectroscopy (FTIR) before and after adsorption in order to determine the functional groups responsible for the adsorption. In all the analyses, three experiments were conducted and mean values reported. The amount of the dye adsorbed per unit mass of the biomass (qe) was calculated and found to be dependent on all the variables investigated. Optimal pH of 2 was determined for the adsorption of Bismarck brown Y dye and Indigo dye, while a pH of 4was determined as the optimal pH for the methylene blue dye. Indigo dye was found to be the least adsorbed while Methylene blue dye was the most adsorbed within the same experimental considerations.
