CTS - 9624724 James Farrell University of Arizona ABSTRACT The project deals with adsorption and transport phenomena in water-saturated microporous materials. The mechanisms controlling the release of hydrophobic contaminants from aquifer sediments will be investigated using both model solids and acquifer sediments. The research will focus on exploring the potential for capillary phase separation (CPS) of a hydrophobic solute within previously water-filled pores of molecular dimensions. The solute-filled micropores may contribute to both adsorption/desorption hysteresis and the desorption resistant fraction. Synthetic zeolites will be used as model sorbents to determine the effects of surface type, pore size, solute hydrophobicity and solute concentration. Temperature programmed desorption experiments and NMR measurements are planned. The research may lead to improved techniques for catalytic destruction of chemical pollutants from manufacturing processes and recovery of organic compounds from aqueous and high humidity vapor streams. The educational plan includes both chemical and environmental engineering students. It focuses on the use of case studies, relevant software packages and research experience for undergraduates.

CTS - 9624724 亚利桑那州詹姆斯·法雷尔大学 摘要 该项目研究水饱和微孔材料中的吸附和传输现象。 将使用模型固体和含水层沉积物来研究控制含水层沉积物中疏水性污染物释放的机制。 该研究将重点探索疏水性溶质在先前充满水的分子尺寸孔隙中进行毛细管相分离（CPS）的潜力。 充满溶质的微孔可能有助于吸附/解吸滞后和解吸阻力部分。 合成沸石将用作模型吸附剂，以确定表面类型、孔径、溶质疏水性和溶质浓度的影响。 计划进行程序升温解吸实验和核磁共振测量。 该研究可能会改进催化破坏制造过程中的化学污染物以及从水和高湿度蒸汽流中回收有机化合物的技术。 教育计划包括化学和环境工程学生。 它侧重于本科生案例研究、相关软件包和研究经验的使用。
