Adsorption of Aromatic Ligand Pollutants onto (Hydro)oxide Minerals in Aquatic Environments

9317842 Stone该奖项旨在为一个项目提供支持，该项目的目标是为模型开发概念和定量基础，这些模型可用于从水溶液中去除芳香族配体污染物的吸附过程的工程设计，并确定这些污染物在通过土壤和地下水含水层时的命运。研究者计划研究影响被吸附物质与吸附介质之间关系的物理和化学因素。该研究包括分析精心挑选的实验结果，旨在提供对吸附过程中涉及的潜在物理和化学现象的良好理解，并将这种理解与模型联系起来，这些模型可能会取代目前表征吸附过程设计和表征的经验主义、特定地点程序。预期该项目的结果将提供比现在更好的基础，以预测通过土壤和含水层移动的水污染物的命运，这些污染物受到水流经的介质表面的吸附。研究结果还可能提高工程师设计土壤修复系统以及水和废水处理过程的能力，这些过程要么基本上基于吸附作为去除污染物的物理过程，要么将吸附作为次要的好处发生。

9317842 Stone This is an award to provide support for a project the objective of which is to develop conceptual and quantitative bases for models that can be used in engineering design of adsorption processes for removing aromatic ligand pollutants from aqueous solution and in determining the fate of these pollutants when moving through soil and groundwater aquifers. The investigator plans on studying the physical and chemical factors that influence the relationship between the substance being adsorbed and the adsorbing medium. The research involves analyzing results of well-selected experiments designed to provide a good understanding of the underlying physical and chemical phenomena involved in the adsorption process and relating this understanding to models that will potentially displace the empirical, site-specific procedures that now characterize the design and characterization of adsorption processes. Results of this project are expected to provide a better basis than now exists for predicting the fate of water pollutants that move through soil and aquifers that are subject to adsorption on surfaces of the media through which the water flows. The results may also provide improvements in the ability of engineers to design soil remediation systems as well as water and wastewater treatment processes that are either fundamentally based on adsorption as the physical process for removal of the pollutants or in which adsorption occurs as a secondary benefit.
