ABSTRACT
stochastic model is applied satisfactorily in simulating the behavior of fixed-bed adsorber and predicting the breakthrough curves for single solute adsorption. A stochastic batch model is applied to estimate the parameters characterizing the transfer process between solid and liquid A stochastic residence time distribution model is employed to estimate the number of compartment and the intensities of forward and backward flow. Such an approach simplifies the problem so that fewer parameters will have to be estimated from any one experiment A sensitivity analysis shows mat this model is very sensitive to the equilibrium capacity through the adsorption period Considering the value of C/C0 of the last segment of the breakthrough curve is only 0.37, and isotherm is assumed to be linear, agreement between the experiment and the model is reasonably good
