The emerging use of scandium and the environmental impact from scandium-containing waste is a rising environmental and health concern. With the development of new materials in the last decade, toxicological studies on those new materials have also been increasing. An example of a process which employs scandium is the generation of metallic nitride fullerene nanomaterials. This process typically generates 99+% scandium waste, as only small amounts of scandium are actually incorporated into the target fullerene molecules. We demonstrate a safe method to recover the scandium content in the waste, reuse the recovered material and successfully demonstrate a comparable product distribution without detectable health and environmental concerns.
钪的新兴用途以及含钪废物对环境的影响正日益引起环境和健康方面的关注。随着过去十年新材料的发展,对这些新材料的毒理学研究也在增加。一个使用钪的过程的例子是金属氮化物富勒烯纳米材料的生成。这个过程通常会产生99%以上的钪废物,因为实际上只有少量钪被纳入目标富勒烯分子中。我们展示了一种安全的方法来回收废物中的钪含量,再利用回收的材料,并成功证明了在没有可检测到的健康和环境问题的情况下具有可比的产品分布。
