A photometric determination method of uranium with chrome azurol S cetyl trimethyl ammonium bromide was studied.The optimium conditions were tested. The interferencewas eliminated by the use of extraction with 5% TOA-ditolyl solvent in 4.5N hydrochloric acid medium. This method was applied to the concentration range of 0.x-2000 ppm uranium.
