Abstract
A kinetic study of the exchange of Mg(I), Ca(II), Sr(II), Ba(II), Mn(II), C o(II), Cu(II) and Zn(II) metal ions for H(I) ions on acrylonitrile based ce rium (IV) phosphate, a fibrous inorganic ion exchanger, has been made. Vari ous useful kinetic parameters such as self-diffusion coefficient (D-0), ene rgy of activation (E-a) energy of activation (Delta S*) have been evaluated and a correlation has been made of these parameters with the ion exchange characteristics of the material.
