Separation and speciation of fission products by zirconium phosphate prepared by solid-solid reaction

Zirconium phosphate hase, been prepared by solid-solid reaction. The charac terization of this inorganic ion exchanger was done with respect to capacit y, pH titration, dissolution, etc. The preconcentration and separation of f ission products, Sr(II), Co(II), Eu(III), Gd(III), Hg(II) and Am(III) has b een achieved from different acidic media, HCl, HNO3, H2SO4, HClO4. The spec iation of these cations in different media has been investigated. From the results obtained it is obvious that these cations can be preconcentrated in ;ow acidic medium, whilst at high acidity in the range 1-2M, they be can se parated from each other.
