Abstract
Ion-exchange selectivities towards oxoanions and halide ions were studied for radio-chemical applications by an amorphous hydrous titanium dioxide (Am-HTDO) as functions of pH and concentration. The selectivity series was found to be Mo(VI)<W(VI)<P(V)<As(V)<Sb(V) for micro-amounts at pH 9 and Br−≈Cl−≪F− for macro-amounts. A feasibility was suggested for radiochemical separations of32P by35Cl(n,α)32P and77Br by75As(α, 2n)77Br, and selective removal of anionic radionuclides.
