The exchange of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) on crystalline zirconium phosphate has been examined. High loadings may be achieved by using dilute acetate solutions of the cations at elevated temperatures. The exchange does not represent a true equilibrium since "site binding" traps the ions within the crystal lattice. This is reflected in the essentially complete removal of ions from solution up to high loadings. Nickel ion represents an exception as it is only loaded to a modest extent. Possible explanations for the observed behavior are presented. © 1976.
