Only industrialized countries use many conventional methods to remove dyes from wastewater. In this thesis, we focus on the absorption process of textile dyes. The treatment is carried out using a biologically absorbent material, in this case cellulose. We analyze the effect of various operational parameters on the amount of absorption, including contact time, initial formulation concentration, and solution pH.frcellulose, adsorption, , colorants, traitement des eaux uséecellulose, adsorption, dyes, water treatment.Thesis
