摘　　要：本文建立了用Ｐ２０４－Ｎ２０５－煤油－Ｃｌ－Ｈ＿２ＳＯ＿４液膜体系分离富集了高纯稀土氧化物中铜、钴、镍、钙、镁等杂质元素的方法，并与火焰原子吸收法相结合，测定氧化镱、氧化钆等样品中的杂质元素，结果令人满意。liquid membrane containing 5%P204 asmobile carrier,4% N205 as surfactant,1.3mol/L HCl and 0.6mol/L H_2SO_4 as strippant inkerosene is used for the separation and enrich-ment of trace copper,cobalt, nickel,calcium andmanganese in highly pure rare earth oxide,Thenthese elements are determined by flame atomicabsorption spectrophotometry,The results showthat this method is simole and fast.The recover-ies are 95%～104%.
