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.

摘要化学和运输系统部门的界面、运输和分离计划正在资助宾夕法尼亚州立大学Sridhar Komarneni博士的研究。Komarneni博士正在开发一种新型的膨胀云母，以去除铅和锶等重的二价阳离子。这种材料是新颖的，因为它选择性地吸附这些警告，并在特定的摄取水平后崩溃，从而防止回换。这项研究将研究吸收动力学和选择性，并将寻求利用X射线衍射和核磁共振分析来表征材料在吸收过程中的特征。这项研究可能会导致开发一种新的材料，能够选择性地去除有毒的重金属污染物。此外，在移除后，材料的可折叠特性意味着污染物以致密的形式密封。这项技术的发展可能会带来去除和包裹有毒金属离子杂质的新方法。
