Modeling of experimental adsorption isotherm data and kinetics data were essential ways for predicting the mechanisms of adsorption, which will lead to an improvement in the area of adsorption science. In this paper, we employed two isotherms model, namely: Langmuir and Freundlich, to correlate four sets of experimental adsorption isotherm data, which were obtained by batch tests in lab. Linear regression analysis was used to evaluate and to determine the best fit isotherm model; the correlation coefficient (R2) was used to evaluate the data. The modeling results showed that linear Freundlich model could fit the data better than Langmuir model, with relatively higher R2 values. The kinetics model of adsorpbents was tested by the pseudo-first order kinetics and pseudo-second order kinetics models. The result showed that the adsorptions of the adsorbates on adsor...
