9307190 Amy This is an award to provide support for research to develop a comprehensive model that describes the competitive sorption of polycyclic aromatic hydrocarbons in water by minerals bound and naturally present organic matter. The investigators plan on relating the transport of hydrophobic organic compounds like polycyclic aromatic hydrocarbons to factors that facilitate or retard them by sorption on materials through which the water flows. The polycyclic aromatic hydrocarbons to be studied span the solubility range from naphthalene to benzo(alpha)anthracene. The natural organic matter will include standard reference humic substances as well as that in natural soils. Minerals used will include quartz, goethite, calcite, kaolinite and montmorillonite alone and in various combinations typical of aquifers. The result of this project is expected to be a mathematical model that describes transport characteristics of polycyclic aromatic hydrocarbons in groundwater when subjected to contact with naturally present organic matter and aquifer minerals. Its potential use will be in the design and operation of processes and systems for remediation of groundwater and soil that has been contaminated with hydrocarbons.

9307190 Amy该奖项旨在为开发一个综合模型的研究提供支持，该模型描述了矿物结合和自然存在的有机物对水中多环芳烃的竞争性吸附。研究人员计划将疏水性有机化合物（如多环芳烃）的运输与通过水流过的材料吸附促进或阻碍它们的因素联系起来。所研究的多环芳烃溶解度范围从萘到苯并（α）蒽。天然有机质包括标准参考腐殖质和天然土壤中的腐殖质。所使用的矿物包括石英、针铁矿、方解石、高岭石和蒙脱石，以及典型的含水层的各种组合。该项目的结果有望成为一个数学模型，描述地下水中多环芳烃与自然存在的有机物质和含水层矿物接触时的运移特征。它的潜在用途将是设计和操作修复被碳氢化合物污染的地下水和土壤的过程和系统。
