The effect of operating varibles like agitation speed, initial concentration and particle size of adsorbent which have influence on the performance of adsorber are studied. Adsorption behavior of adsorbers are analyzed by introducing the film-solid diffusion model(F-S model) and film-pore diffusion model(F-P model). Both of the models can be applied to predict the performance of adsorbers. F-P model is slightly better than F-S model to represent the ex-perimental data. The eftect of initial concentration on the pore diffusivity is so strong that in the region of influence, it is recommended to use F-S model.
