title: Intraparticle diffusion of a basic dye during adsorption onto sphagnum peat.
abstract: The adsorption of a basic dye from aqueous solutions onto peat has been examined. Intraparticle diffusion in the peat pore structure is proposed as a mass transfer mechanism. The results indicate a diffusion process in occurring by a macropore and micropore controlled process. A diffusion rate parameter, k, is proposed and is correlated with possible system variables.
