In this research, batch kinetic experiments were carried out for the sorption of Reactive Red 198 onto magnetic activated carbon. Effect of pH and contact time on the adsorption process was studied. The equilibrium time decreased with agitation of solution. The experimental kinetic data were fitted to the pseudo-first order, pseudo-second order, and intra-particle diffusion models by linear and non-linear methods using Mathematica software. The results showed that non-linear method is the most appropriate method to predict the rate kinetic parameters. Also, dye adsorption kinetics followed both pseudo-second order and intra-particle diffusion models.
