Determination of uranium content Polarographic method1 ScopeGB/T 13747 provisions of this part of zirconium and zirconium alloys Determination of uranium content. This section applies to sponge zirconium, zirconium and zirconium alloy determination of uranium content. Measuring range. 0.00010% to 0.00050%.2 method summaryHydrofluoric acid was used to dissolve the sample, and the nitric acid was added dropwise to dissolve the insoluble carbides or nitrides. The mixture was extracted with tributyl phosphate-toluene in a nitric acid medium Separation of uranium.
