The use of disodium 1,8-dihydroxynaphthalene-3,6disulfonate (chromotropic salt) as a reagent for the determination of uranium on a micro- scale is described. The reagent is sensitive to 30 ppm of uranium, and Beer's law holds good in the range of concentration of 50 to 200 ppm. The reagent added should be at least 30 times the molar concentration of uranium. The pH of the medium should bo adjusted at 4.00 plus or minus 0.50. For the determination, either a photoelectric colorimeter with a blue filter or a spectrophotometer can be employed. The interference of various cations and anions has also been studied. The chelate has a composition of 1.1 of the reactants. auth)
