A sensitive and rapid radiochemical method has been developed for the determination of microgram amounts of indium(III) based on the substoichiometric extraction of its 1∶3 complex with potassium ethyl xanthate from pH 7 ammonia buffer into chloroform. 5–50 μg of indium was determined with an average error of 1.56%. The effect of associated species on the extraction was studied.
