| Description |
The recovery of acetic acid from industrial wastewaters is an important separation
problem, and one of the routes suggested for this application is liquid phase
adsorption on activated carbon adsorbents. Designing an adsorber for such applications
requires knowledge of equilibrium isotherm as well as adsorption rate
data. In the present work the kinetics of adsorption of acetic acid on activated
carbon has been studied. A three-parameter isotherm model has been used to
correlate the equilibrium data, and a combined external film transfer-surface diffusion
model has been used to simulate the experimental adsorption rate data. The
surface diffusivity values obtained range from 6 to 8.5 x lo-’ cm%, and the
values show a dependence on surface loading. These surface diffusivity values
can be used in modeling the column breakthrough behavior for this system.
