Abstract

Previous studies indicated that phenol transport from spilled bitumen to aquifer was controlled by slow molecular diffusion of phenol in bitumen as the rate-determining step so that it could be de-coupled from the aquifer flow equation, leading to time-dependent phenol concentration in a flowing stream. This study presents a new model by incorporating reversible adsorption of phenol into the flow equations using a chromatographic transformation technique. Results showed that adsorption retarded phenol propagation by a delay factor related to the adsorption/desorption characteristics. This model enhanced with adsorption capability is well suited to other water pollution problems arising from chemical spills.
