Novel Swelling Mica for Cation Separations

摘要 化学和运输系统部的界面、运输和分离项目正在资助宾夕法尼亚州立大学的Sridhar Komarneni博士的研究。 Komarneni博士正在开发一种新型的膨胀云母，以去除重的二价阳离子，如铅和锶。 该材料是新颖的，因为它选择性地吸附这些谨慎，并在特定的吸收水平后，崩溃，从而防止反交换。 该研究将解决吸收动力学和选择性，并将寻求在吸收过程中使用X射线衍射和NMR分析来表征材料。 这项研究可能会导致开发一种能够选择性去除有毒重金属污染物的新型材料。 此外，在移除之后，材料的可塌缩性质意味着污染物以压实形式密封。 这项技术的发展可能会导致新的方法来去除和封装有毒金属离子杂质。

ABSTRACT The Interfacial, Transport, and Separations Programs of the Chemical and Transport Systems Division is funding research of Dr. Sridhar Komarneni, at the Pennsylvania State University. Dr. Komarneni is working on developing a novel swelling mica to remove heavy, divalent cations such as lead and strontium. The material is novel in that it selectively adsorbs these cautions and after a specific uptake level, collapses, thus preventing back-exchange. The research will address the uptake kinetics and selectivity's, and will seek to characterize the material during the uptake process using X-ray diffraction and NMR analysis. This research may lead to the development of a novel material capable of selectively removing toxic, heavy metal contaminants. Additionally, after removal, the collapsible nature of the material implies that the contaminants are sealed in a compacted form. Development of this technology may lead to new methods to remove and encapsulate toxic metal ion impurities.
