T he results were compared to those obtained from traditional batch exchange method. Contact time, initial cation concentration insert ignore into journalissuearticles values(fold equivalent excess); and the types of the ultrasound were studied. U ltrasonic probe, which is the most effective method, enhanced th e replacement of Na + ion with Ce 3+ ion in the extra-framework of zeolite up to 73 % by applying 5 consecutive ion exchanges . The cerium in the solution caused to be formed cerium oxides on the crystal surface occluding the pores. Thus the specific surface area of cerium exchanged zeolite was decreased due to formation of cerium complexes on the surface and into the pores.
