This research project, supported in the Analytical and Surface Chemistry Program, explores the mechanisms and kinetics of the reactions of chlorinated hydrocarbons on iron and palladium surfaces. Using a unique suite of experimental tools, including laser induced thermal desorption and reflection absorption infrared spectroscopy, developed in Professor Donald P. Land's laboratory, Land and his colleagues at the University of California-Davis are obtaining kinetic information about the decomposition of chloroethylenes on well characterized iron and palladium in ultra-high vacuum. These model studies promise a fundamental understanding of reactions that are important in wastewater remediation chemistry. In addition, the work provides basic molecular level information about an important class of surface reactions. The decomposition of chlorine containing hydrocarbon compounds is of significant relevance to the remediation of wastewaters and ground waters in industrialized areas. The work carried out in this project at the University of California-Davis is exploring the detailed molecular mechanisms of these reactions on well characterized metal surfaces. The insight gained from these studies will enhance clean-up strategies, as well as provide fundamental understanding of an important class of surface reactions.

这项研究项目由分析和表面化学计划资助，探索氯代烃在铁和钯表面反应的机理和动力学。利用唐纳德·P·兰德教授的实验室开发的一套独特的实验工具，包括激光诱导热解吸和反射吸收红外光谱，兰德和他在加州大学戴维斯分校的同事们正在获得关于氯乙烯在超高真空中在特征良好的铁和钯上分解的动力学信息。这些模型研究承诺对废水修复化学中重要的反应有一个基本的理解。此外，这项工作还提供了一类重要的表面反应的基本分子水平信息。含氯碳氢化合物的分解与工业化地区废水和地下水的修复密切相关。加州大学戴维斯分校的这项研究正在探索这些反应在特征良好的金属表面上发生的详细分子机制。从这些研究中获得的洞察力将加强清理策略，并提供对一类重要的表面反应的基本理解。
