Separation of scandium(III) from iron(III), molybdenum(VI), vanadium(V), chromium(VI), titanium(IV), bismuth(III), zirconium(IV), lanthanum(III), and thorium(IV) is achieved by solvent extraction with mesityl oxide from sodium sallcylate solution (0.1 M) adjusted to pH 4. Scandium from the organic phase is stripped with water and determined photometrically as its arsenazo complex at 570 nm. The extracted species is trisolvated, i.e., Sc(HOC/sub 6/H/sub 4/COO)/sub 3/3Me0. 1 figure, 1 table.
