Shaping the future with Rare Earth Elements – Model Experiments for “damage monitoring” with [Eu(DBM)4TEA] and for Recycling of Neodymium(III) Sulfate from Hard Disk Magnets

摘要

Rare Earth Elements (REEs: Sc, Y, La–Lu) are found in numerous future-oriented applications such as in magnets for green technologies and in fluorescing materials. A shortage of resources is already forecast for diverse REEs, which suggests it may be necessary to recycle these elements and optimize technologies. Both aspects will be addressed in this paper. Model experiments with regards to damage monitoring using [Eu(DBM)4TEA] and the recycling of neodymium(III) sulfate in hard disk magnets will also be presented. These are experiments for teachers and students who already have advanced experimental experience, such as trainees at vocational schools.
