Abstract
Textile industries release large amounts of wastewater at risk of toxicity. Shells could be alternative adsorbent materials both economic and less polluting. To highlight the process of adsorption of dyes on Mytilus Edulis shells, a model, based on an analytical method was applied to the case of spherical samples. The theoretical, results fo the kinetics of dye transfer were in good agreement with the corresponding experimental ones. The Spherical model exhibited a significant dye transfer, controlled by diffusion with different diffusivity an a coefficient of matter transfer characterizing the retardation in the transfer on the surface.
