Herein, we report an elaborate method, size-selective crystallization of Ln-MOFs, to isolate lanthanide (Ln) ions. Herein, 13 lanthanide ions, except for the radioactive Pm(iii) ion, were separated by four types of Ln-MOFs: type I (La-Pr), type II (Nd-Eu), type III (Gd-Ho), and type IV (Er-Lu). Further systemic investigation also suggested the highly selective separation of lanthanide ions by this method.
在此，我们报道了一种精细的方法——镧系金属有机框架（Ln-MOFs）的尺寸选择性结晶，用于分离镧系（Ln）离子。在此，除放射性的钷（III）离子外，13种镧系离子通过四种类型的Ln-MOFs进行了分离：I型（镧-镨）、II型（钕-铕）、III型（钆-钬）和IV型（铒-镥）。进一步的系统研究还表明，该方法对镧系离子具有高度选择性分离效果。
