Abstract:The adsorption of water in ethyl acetate on zeolite 3A was carried out in a batch system.The equilibrium behaviour was shown to fit a Langmuir isotherm.A surface diffusion model,coupled with the observed Langmuir isotherm equations,was used to interpret the observed experimental adsorption kinetic curves at(different) initial concentrations,temperatures and particle sizes.Surface diffusivity D_(s) can be calculated.The surface diffusivity increased as temperature and initial concentration increased,but it was independent of particles size.The pre-exponential factor D_(so) and the activation energy E was also calculated.
Keywords:ethyl acetate  water  adsorption kinetics  surface diffusivity  zeolite 3A
