Two component separations involving titanium(IV), zirconium(IV), iron(III), aluminum(III), gallium(III), indium(III), copper(II) and zinc(II) were carried out by using a column (i.d. 0.9 cm, height 10cm) of Amberlite IR-120 {(60〜100) mesh} in the hydrogen form. 5×10^<-5> mol each of metallic element was loaded on to the top of the column. After washing the column the eluant was passed down the column at a flow rate of 0.5cm^3 min^<-1>, and the metal in each fraction (10cm^3) of the effluent was determined chelatometrically after decomposition of the oxalato complex and excess oxalic acid with ammonium peroxodisulfate. Complete separations were achieved of titanium from aluminum, titanium from copper, zirconium from aluminum, iron from aluminum with 0.05M oxalic acid-0.4M hydrochloric acid, gallium from indium with 0.05M oxalic acid-0.2M hydrochloric acid, indium from zinc with 0.05M oxalic acid-0.6M hydrochloric acid, zirconium from titanium with 0.02M oxalic acid-0.12M hydrochloric acid, zirconium from copper with 0.01M oxalic acid-0.02M hydrochloric acid, and zirconium from iron with 0.005M oxalic acid-0.01M hydrochloric acid.
