ABSORPTIOMETRIC DETERMINATION OF IRON IN URANIUM AND ITS COMPOUNDS. URANIUM METAL, AMMONIUM DIURANATE AND URANOUS FLUORIDE (AFTER REMOVAL OF FLUORINE)
The possibility of determining microgram quantities of iron in uranium solutions using thioglycolic acid and ammonia without a prior separation from uranium has been studied and a method proposed. Citrate and carbonate ions are employed to prevent precipitation of uranium and destroy the color due to uranium and thioglycolic acid, respectively. Solutions containing uranyl ions do not absorb light at 5350 A which corresponds to maximum absorption for iron thioglycolate. Cobalt interferes and as yet the method can only be applied where this metal is absent or present in relatively small quantities. The method has been successfully applied to solutions of uranium metal (in nitric acid), ammonium diuranate, and uranlum tetrafiuoride after removal of fluorine. (auth)
