文摘
This work consists with the use of a Na-Y zeolite for the recovery of Ni2+, Pb2+, Zn2+, Cr6+, Cd2+ and Co2+ ions starting from prepared aqueous solutions by batch process mode. Zeolite Na-Y was characterized by XRD, SEM and EDS techniques. The sodium exchanged ions existing in zeolite were measured by a potentiometric technique, based to the measure of the potential of selective sodium electrode. The ion effect on the exchange percentage of zeolite Na-Y was study. Kinetic, equilibrium and thermodynamic studies were also carried out. The obtained results show that zeolite Na-Y is effective in the recovery of the studied ions.
