The anion exchange behaviour of first row transition elements Manganese to Zinc has been studied over Zirconyl Silicate in hydrochloric acid (0.3-3.0M) as eluent The adsorption of these elements changes sufficiently as a function of hydrochloric acid concentration to permit their separation The adsorption and stability of negatively charged complexes is found to be in the order of Ni(II) < Mn (II) < Cu (II) < Cr (III) < (Co (II) < Zn (II) < Fe (II). Unlike other elements studied, adsorption of Ni(II) is very small which decreases as the concentration of hydrochloric acid is increased.
