Three‐Resistance Transport Model for Dye Adsorption onto Bagasse Pith
Publication: Journal of Environmental Engineering
Volume 116, Issue 3
Abstract
The adsorption of two dyestuffs from aqueous solutions onto bagasse pith was studied using an agitated batch adsorber. A three‐resistance mass transfer model, based on external mass transport, macropore diffusion, and micropore diffusion, was used to predict concentration versus time decay curves. The predicted curves were correlated with experimental data for up to 24 hours in order to determine the three mass transport parameters.
