Novel Swelling Mica for Cation Separations

宾夕法尼亚州立大学化学与传输系统部的界面、传输和分离项目资助了Sridhar komareni博士的研究。科马尼尼博士正在开发一种新型浮肿云母，以去除铅和锶等重的二价阳离子。这种材料的新颖之处在于，它可以选择性地吸附这些物质，并在达到特定的吸收水平后坍塌，从而防止反交换。该研究将解决摄取动力学和选择性，并将寻求在摄取过程中使用x射线衍射和核磁共振分析表征材料。这项研究可能会导致一种能够选择性去除有毒重金属污染物的新型材料的发展。此外，在去除后，材料的可折叠性质意味着污染物以压缩形式密封。该技术的发展可能会带来去除和封装有毒金属离子杂质的新方法。

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.
