Presidential Young Investigators Award: Research in Aquatic Surface Chemistry Related to Solute Transport in Soil & Aquifers & in Adsorption Treatment of Water & Wa

这是一个支持研究的奖项，其目的是比目前更好地了解离子溶质(主要是金属)在地下环境、水和废水处理吸附过程以及受污染土壤处理过程中的去向和迁移。工作包括确定溶质在颗粒上的沉淀机制，以及腐殖质材料涂层对矿物表面和吸附性能的影响。将研究溶质的竞争吸附，特别是痕量金属与主要电解液离子之间的竞争吸附。这项奖励为这位总统青年调查员提供了初步的基础支持，并提供了与宾夕法尼亚州匹兹堡钱伯斯发展公司提供的37500美元相匹配的资金。预计结果将促进我们目前对水溶液离子溶质吸附机理的理解，提高现有吸附模型的有用性，这些模型用于水和废水处理过程的设计，预测污染物在含水层中的移动，以及用于净化土壤的系统的工程设计。

This is an award to support research the objective of which is to obtain a better understanding than now exists of the fate and transport of ionic solutes (primarily metals) in the subsurface environment, in adsorption processes for treatment of water and wastewater and in processes for treatment of contaminated soils. Work includes determining the mechanisms of solute precipitation on particles and the influence of humic material coatings on surface and sorptive properties of minerals. Competitive sorption of solutes will be studied especially between trace metals and major electrolyte ions. This award provides initial base-level support for this Presidential Young Investigator and funds to match $37,500 provided by the Chambers Development Corporation of Pittsburgh, Pennsylvania. Results are expected to advance the understanding we now have of adsorption mechanisms for aqueous ionic solutes, to enhance the usefulness of existing adsorption models that are used in design of processes for treatment of water and wastewater, in predicting the movement of pollutants in aquifers, and in engineering design of systems to decontaminate soil.
