dc.description.abstract | This study relates to the movement of Zr,+4,Co+2, Rh+3, Ir+3 and Mo+3 ions relative to Ni+2 ion when impregnated on gamma alumina cylindrical pellet (dia. 2.5 mm). In general, with the increase in soaking time and at higher solution concentration, the metallic ions penetrated deep into the pellet. The preferential adsorption of ions of Zr,+4,Co+2, Ir+3 and Mo+3 at the periphery with respect to ions of Ni+2 is due to higher ionic charge density on these ions, whereas the restricted movement of Zr,+4 ion, besides higher ionic charge, is also due to its bigger ionic radius | en_US |
