摘要: AbstractThis study was aimed at investigating the sorption of Ni(II) ions on anode dust which is an industrial waste material aluminium production. The effects various parameters such as initial pH, contact time, temperature and concentration were studied. thermodynamic determined. positive values enthalpy change ΔH suggested endothermic nature process. kinetic data could be described well using a pseudo‐second‐order model equilibrium fitted to Langmuir Freundlich isotherm. It can concluded that obtained capacity for good indicator potential use in aqueous system.Cette etude avait pour but l’investigation de la des sur poussiere d’anode, un materiau rejet industriel production l’aluminium. On etudie l’effet divers parametres comme le pH initial, duree contact, temperature, et ...
