The development of a method for the estimation of uranium (in concentrations of the order of 1 ppm) in dibutyl carbitol is reported. Main techniques investigated were: water extraction of the uranium followed by an absorptiometric determination, employing the coloration produced by the addition of hydrogen peroxide to solutions of uranium in sodium carbonate solution: direct fluorimetric estimation of the evaporated dibutyl carbitol solution; and chromatographic separation of the uranium on paper strips by the C.R.L. technique prior to fiuorimetric estimation. The report shows that the lower limit for the colorimetric method is 200 microgram/ml and that the fluorimetric method is adequate for the range 0-200 microgram/ml. (auth)
