Indium is separated from tin by an anion-exchange process in 0.5M hydrochloric acid solution. Subsequently, the indium is extracted into 1,2- dichlorobenzene as its complex with 5,7-dichloro-8-quinolinol. The complex forms and extracts quantitatively in the pH range 3-7. The yellow, organic phase is measured spectrophotometrically at 415 m mu ; its absorbancy is directly proportional to the indium content of the aqueous phase up to a total of 1.5 mg of indium per 50 ml. This procedure quantitatively separates the two metals, allows one to determine the indium content of indium (<5%)--tin alloys with a relative error less than 0.7%, and considerably reduces color fading errors.
