Synthetic inorganic ion exchanger. IX. Thorium antimonate. Synthesis,properties and ion exchange separations

Summary Thorium antimonate has been synthesised by mixing 0.1 M Th(NO₃)₄ solution in 0.1 N HNO₃ and 0.05 M potassium pyroantimonate and by mixing 0.1 M Th(NO₃)₄ solution in 0.1 N HNO₃ with 0.1 M SbCl₅ in 4N HCl at controlled pH. The preparative procedure, composition, I.R. spectra, chemical and thermal stability, physico-chemical properties and distribution coefficients of metal ions on thorium antimonate have been determined at pH 5.5–6.5. On the basis of distribution co-efficient values separations of Cu(II) from Mg(II), Ni(II), Mn(II), Mg(II), from Zn(II) and Cd(II) and Zn(II) from Cd(II) have been achieved. Part VIII: Reference [1]
