Metal Ion Speciation at Aqueous/Solid Interfaces

化学学部的环境化学（ECS）项目将支持美国西北大学Franz Geiger教授的研究项目。盖格教授的研究项目侧重于首次应用一种独特的光谱方法，称为Eisenthal chi(3)方法，研究金属阳离子在矿物表面的吸附。Eisenthal chi(3)方法对界面电位具有独特的敏感性，可以看作是一个光学电压表。如果成功，该研究将为环境科学家提供一种新的、广泛适用的研究矿物表面离子吸附的工具。该项目有可能改变我们对复杂环境系统中界面现象的理解。该项目将为渴望在环境科学前沿工作的学员提供良好的教育机会。

The Environmental Chemical sciences (ECS) program of the Division of Chemistry will support the research program of Prof. Franz Geiger of Northwestern University. Prof. Geiger's research program focuses on the application for the first time of a unique spectroscopic method, named the Eisenthal chi(3) method, to study the adsorption of metal cations on mineral surfaces. The Eisenthal chi(3)method is uniquely sensitive to the interfacial potential and can be viewed as an Optical Voltmeter. If successful, the study will provide environmental scientists with a new and widely applicable tool for studying ion adsorption on mineral surfaces. The project has the potential to transform our understanding of interfacial phenomena in complex environmental systems. The project will provide excellent educational opportunities for trainees desiring to work at the forefront of environmental science.
