| 摘 要： | 氟碳铈矿矿样经高氟酸分解、脱硅后，稀土元素以氢氧化物和草酸盐形成进行沉淀与干扰元素分离，氢氧化物沉淀使稀土与钙、镁分离，草酸盐沉淀，使稀土与铁、铝、锆、钛等元素分离。适应矿石稀土含量１％～７４％的含量测定。该方法用于氟硕铈矿稀土总量的测定，方法简便、快速、准确。

| Abstract: | A new method applying to determination of total REE in bastnaesite in Sichuan is proposed in this paper Bastnaesite sample is decomposed and desilicated by perchloric acid Rare earth elements are precipitated in hydroxides and Oxalates and separated from interference elements Rare earth elements are separated from Ca, Mg by precipitation of hydroxides and from Fe,Al,U,Zr,Ti, etc by precipitation of oxalates The method has been applied to the determination of 1%-7% REE in bastnaesite The method is simple,fast and precise |
