“…Several papers described methods for the determination of hafnium in zirconium (277,453,551,552,574). Hafnium was also determined in mixtures (276), in aluminum (21,47,370) and in sand (553). Most of these procedures involve an ion-exchange or precipitation separation.…”

“…An ion-exchange concentration was used in conjunction with neutron activation for the determination of vanadium in sodium chloride (771). Vanadium was separated from aluminum by cupferron extraction in the determination of impurities in aluminum (370). A study was made of the determination of aluminum and vanadium when the aluminum to vanadium ratio was between 1 and 60 (17).…”

“…The separation of chromium from the matrix and other impurities in the analysis of aluminum was achieved by solvent extraction (21), and ion-exchange combined with solvent extraction (47,370,530). The impurities in germanium were determined by a nondestructive technique (534).…”

“…and 3547.74-2576.10 -1. were used to plot a calibration curve. Kiesl, Rildstein, and Sorantin (90) employed activation analysis for the determination of manganese and gallium in aluminum as described in the Gallium section. Tikhonov and Nikitina (181) reported the determination of small quantities of manganese in magnesium alloys with rare earths by oxidation with KIO, after extraction with a CCI, solution of sodium diethyldithiocarbamate.…”

“…Methyl Glycol System. Determinations of the distribution coefficients of aluminum, gallium, and indium at varying 2-methoxyethanol-l concentrations at a constant overall hydrochloric acid concentration of 0.6 7 (10% 6Ar hydrochloric acid in the mixtures) have shown (see Table 1) that in the region from 70 to 90% 2-methoxyethanol-l the separation factor of indium in respect to gallium is approximately 3 Since aluminum is practically nonabsorbable under these conditions the separation factor between this element and gallium or indium is Separation of Ga, In, and Al in acetone-HCI media even much higher, so that easy separation is feasible.…”
