Abstract

The distribution coefficients of alkaline earth metal ions were measured on crystalline hydrous titanium dioxide fibers at 298K. The adsorption behavior of these ions was well explained by their ion-exchange reaction with hydrogen-ions in the fibers. The distribution coefficients of alkaline earth metals were determined as a function of pH. Separation of strontium(II) from barium(II) was achieved by using a column of this ion-exchanger with hydrochloric acid solutions as an eluent.
