Ｕ３Ｏ８试样用硝酸分解后，用ＴＢＰ－ＣＣｌ４溶液萃取分离铀，水相用ＨＣｌＯ４蒸干，残渣溶于０．０５ｍｏｌ／Ｌ的ＨＣｌＯ４和０．０３ｍｏｌ／Ｌ的酒石酸混合底液中，用方波阳极溶出伏安法测定Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ，然后用氨水调节ｐＨ为９．５，用方波极谱法测定Ｆｅ、Ｍｎ，最后加入２０μＬ丁二酮肟用络合物吸附波催化方波极谱法测定Ｎｉ、Ｃｏ．标样测定结果接近给出的中位值，精密度高．变异系数在２．１％－９．７％之间。
U3O8 samples were decomposed with nitric acid, TBP-CCl4 solution was used for extraction and separation of uranium, the water phase was evaporated to dryness with HClO4, the residue was dissolved in 0.05mol / L HClO4 and 0.03mol / L tartaric acid mixed base solution, with a square wave Anodic stripping voltammetry for the determination of Cu, Pb, Zn, Cd, and then adjusted to pH 9.5 with ammonia, using square wave polarography determination of Fe, Mn, finally added 20μL dimethylglyoxime with complex adsorption wave catalytic side Polarographic determination of Ni, Co. The standard sample results close to the median given, high precision. The coefficient of variation is between 2.1% and 9.7%.
