摘要：
It vas found from experiments that adsorption of Cd and Zn in the dynamic system was higher than that in the static systea. Equilibrium Adsorption Model (EAM) and Two Site Adsorption Model (TSAM) have been validated with the observed concentration history curves of Cd and Zn. In most of the cases the EAM model with dynamic isotherm constants fitted the observed concentration history curves satisfactorily. In those where EAM did not fit well (using Dynamic isotherm constants), the TSAM predicted more accurately. The general conclusion is that for highly adsorbing solutes, EAM is a simple and quite satisfactory model for the prediction of concentration profiles both temporally and spatially. © 1990 Publications Division Selper Ltd.
