Nuclide separation properties by highly functional microcapsules were evaluated and compact precise separation process was developed. Microcapsules enclosing AMP, crown compound, insoluble ferrocyanides and extractants (MIDOA, TOA and LIX) were effective for the separation of Cs, Sr, Pd,Tc, Re, and Mo, respectively, and applicability to simulated and real wastes was confirmed.

评估了高功能微胶囊的核素分离性能，并开发了紧凑的精密分离工艺。封装 AMP、冠状化合物、不溶性亚铁氰化物和萃取剂（MIDOA、TOA 和 LIX）的微胶囊分别可有效分离 Cs、Sr、Pd、Tc、Re 和 Mo，并且证实了其对模拟废物和真实废物的适用性。
