|Abstract: ||Gallium was extracted at pH 4-6 with 0.1 mol l-1 Aliquat 336S in xylene as anionic ascorbate complex. It was stripped from the organic phase with 1 mol l-1 nitric acid and was determined by spectrophotometry at 510 nm as a complex with 4-(2-pyridylazo)resorcinol. Gallium was separated not only from aluminium, indium, thallium(III) but also from iron(II), vanadium(IV) and scandium which metals are generally associated with it in minerals and alloys. The method was extended for analysis of gallium in high purity aluminium.|
