THE SPECTROGRAPHIC DETERMINATION OF TRACE AMOUNTS OF INDIUM IN URANIUM METAL

Technical Report ·
OSTI ID:4269353
A solution of indium, at a controlled pH, is extracted with dithizone in the presence of ammonium citrate and cupferron. The dithizonates are absorbed on a column of activated alumina and the indium-containing portion of the column mixed with an internal standard/carrier mixture and spectrographed by a carrier distillation technique. Evaluation is by means of a microphotometer, using an internal standard. The method is suitable for indium concentrators in the range 0.01 to 0.1 ppm. (auth)
