In sulfuric acid medium at pH 2-3,uranium can be sorbed by 30mg of Type -742 anion resin (250-400) in competing eqilibrious sorption. Then the resin and the sorbed uranium is filtered on a circular paper. Intensity is measured by VRAXRF-spectrograph using a x-ray tube with a Mo anode at 50 KV, U La I ray and a LiF crystal analyser The method has been used for determination of uranium (0.00X-X%) in ores and samples of mineral-dressing and metallurgy.
