Packed bed adsorption of various pollutants from effluents is efficient and cost effects method. Various factors affecting the removal percentage are initial concentration, flow rate, pH and bed height. Various models can be used to explain the packed bed adsorption. In the current work, the experimental data obtained for packed bed is fitted in the two model equations. Thomas model and Yoon Nelson model were used and the kinetic parameters were computed. Also effect of the factors like initial concentration, flow rate, pH and bed height on these kinetic parameters was studied. It was observed that these factors moderately influence the kinetic parameters. The experimental data was well described by these two models.
