    摘要： An object of the present invention is to provide a method for separating and refining scandium capable of efficiently separating and refining the scandium from a solution containing the scandium, with improved stripping, while securing separability (selectivity) of the scandium from impurity elements. The method of the present invention involves mixing a solution containing the scandium with an organic solvent containing a trioctylphosphine oxide to extract the scandium into the organic solvent; and mixing the organic solvent with a stripping starting solution containing any one or more of water, hydrochloric acid, sulfuric acid, and oxalic acid to strip the scandium from the organic solvent.

    摘要： Processes described include reacting a fresh or spent catalyst, or sorbent, with a solution containing an extracting agent (such as an acid or a base). Preferably, the catalyst contains both alumina and a molecular sieve (or a sorbent), and the reaction is performed under relatively mild conditions such that the majority of the base material does not dissolve into the solution. Thus, the catalyst can be re-used, and in certain instances the catalyst performance even improves, with or without re-incorporating certain of the metals back into the catalyst. Additionally, metals contained in the catalyst, such as Na, Mg, Al, P, S, Cl, K, Ca, V, Fe, Ni, Cu, Zn, Sr, Zn Sb, Ba, La, Ce, Pr, Nd, Pb, or their equivalent oxides, can be removed from the catalyst. Some of the metals that are removed are relatively valuable (such as the rare earth elements of La, Ce, Pr and Nd).
