Quantitative separation of titanium from numerous metal ions and of iron, aluminum and titanium by paper chromatography

Abstract

Titanium has been quantitatively separated from numerous metal ions using formic acid—hydrochloric acid—acetone (3:5:2). The method has been found useful for the quantitative separation of about 200 μg of titanium from a synthetic mixture of 17 metal ions including Mo 6+, W 6+, Cu 2+, Fe 3+, Al 3+, Cr 3+, Ni 2+, Co 2+, Mn 2+, UO 2+ 2 and V 4+. Quantitative separation of Fe 3+Al 3+Ti 4+ has been achieved using formic acid—hydrochloric acid—acetone (3:4:3). Both separations are fast and selective.
