A Kinetic Study for Removal of Bismarck Brown G by Adsorption Over Prepared Supported (Co, Ni)3O4/Al2O3 Spinel Catalyst

Emman J. Mohammad, Salih H. Kathim and Abbas J. Lafta


The supported co-catalyst (Co, Ni)3O4/Al2O3 was prepared via co-precipitation method. Two sets of these materials were prepared by calcination at two temperatures 500, and 600oC. Crystal structure of the prepared materials was investigated using powder X-rays diffraction (PXRD), and specific surface area (BET). The adsorption ability of the prepared catalyst (Co, Ni)3O4/Al2O3 was investigated by adsorption of Bismarck brown G dye (BBG) from simulated industrial wastewaters. Equilibrium adsorption isotherms and kinetics studies were investigated. The experimental data were analyzed according to Freundlich and Langmuir models of adsorption. The adsorption isotherms data were fitted well to Langmuir isotherm and the kinetic data were fitted very well with the pseudo-second-order kinetic model.
