Abstract :
Oxidized di(2-ethylhexyl)dithiophoshate (Phoslex DT-8) in n-hexane is shown to extract Sc(III) greater than 97% in the pH range of 1.01–4.46, while ZrO(II) is not extracted under the same conditions. Phoslex DT-8 was oxidized by blowing air in it, and the percent extraction of Sc(III) increased along with the duration of air-oxidation. The present extraction system can be used to separate Sc(III) from ZrO(II), Ti(III), Y(III) and Al(III) in a single batchwise extraction.
