The adsorption of nickel and iron from liquid solutions by coke breeze (CB) has been investigated. The process was studied in a batch system with respect to the initial pH, contact time, temperature, adsorbent dose and metals initial concentration. The results showed that the experimental data was well represented by second order reaction for nickel and first order for iron. Based on the kinetic modeling the values of activation energy were 51.92 KJ/mole for nickel and 8.936 KJ/mole for iron. The equilibrium data for CB indicated that that adsorption of nickel followed Langmuir isotherm and iron followed Freundlich isotherm. The thermodynamic parameters (∆Ho, ∆So and ∆Go) calculated from the experimental data indicated that the process was endothermic and spontaneous.
