Abstract: The fixed bed adsorption of Acid Blue 80 (AB80) onto granular activated carbon (Chemviron Filtrasorb 400) has been studied using a Homogeneous Surface Diffusion Model (HSDM). The model incorporates the external boundary layer mass transport and homogeneous diffusion inside the particle. An orthogonal collocation method has been used to solve the diffusion equations.
