Newer materials for separating environmentally-undesirable ions from waste waters and nuclear wastes are needed to meet the stringent waste-treatment requirements. Such materials are also important in the recovery of valuable metals and minerals from solutions. This program is designed to evaluate the basic chemical properties and characteristics of a new class of ion- exchange materials developed by the principal investigators at the Materials Research Laboratory of the Pennsylvania State University. The new ion exchangers promise to have larger capacity than the currently-available ones and have the potential to be of use in a large number of separation processes.

为了满足严格的废物处理要求，需要更新的材料从废水和核废料中分离出对环境有害的离子。这种材料在从溶液中回收有价值的金属和矿物方面也很重要。该计划旨在评估宾夕法尼亚州立大学材料研究实验室的主要研究人员开发的一种新型离子交换材料的基本化学性质和特征。新的离子交换器承诺具有比目前可用的离子交换器更大的容量，并有可能用于大量的分离过程。
