The project aims to develop a novel hydrometallurgical method for the separation of the rare earth metals dysprosium and terbium from mixed rare earth metal solutions using polymer inclusion membranes with a crosslinked or non-crosslinked polymer backbone. These metals are crucial for the manufacturing of advanced technology products. The membrane-based method is expected to offer significant advantages over the currently used solvent extraction methods by eliminating the use of solvents and conducting the separation as a continuous process where the extraction and back-extraction steps take place simultaneously. These advantages are expected to make the separation process more cost-effective and drastically reduce its environmental impact.

该项目旨在开发一种新的湿法冶金方法，利用具有交联或非交联聚合物骨架的聚合物包合膜从混合稀土金属溶液中分离稀土金属镝和铽。这些金属对于制造先进技术产品至关重要。基于膜的方法预计将提供显着的优势，目前使用的溶剂提取方法，通过消除溶剂的使用，并进行分离作为一个连续的过程中，提取和反萃取步骤同时发生。这些优点预计将使分离过程更具成本效益，并大大减少其对环境的影响。
