本文报道了应用ЛЮФ-57型光电荧光仪测定痕量铀的方法。采用碳酸钠沉淀法及乙酸乙酯萃取法分离干扰元素。可测定2×10~(-8)克铀,方法误差为±6%。
In this paper, a method for the determination of trace uranium using ЛЮФ-57 photoelectric fluorometer was reported. Interference elements were separated by sodium carbonate precipitation and ethyl acetate extraction. Can measure 2 × 10 ~ (8) grams of uranium, the method error is ± 6%.
