Gas-Solid Phase Reactions of Organic Compounds on Fly Ash

这项研究的目的是提供一个更好的理解化学转化和化学化合物的环境命运在大气中与空气中的颗粒物相互作用。虽然许多气体化学转化（均相）已被很好地记录下来，但非均相反应却鲜为人知。理论预测、基础实验室研究和实地调查相结合，支持非均相反应可能是重要的大气化学过程的结论。这项工作的一个目标是提高研究大气中非均相化学转化的能力。这个研究项目可能会导致大气系统中化学反应性的新概念。该项目的具体目标是：(1)提高对大气非均相化学反应的认识；(2)确定气体和复杂大气气溶胶之间化学反应的趋势、模式和行为。

This research is aimed at providing an improved understanding of the chemical transformations and environmental fates of chemical compounds in the atmosphere that interact with airborne particulate matter. While many gaseous chemical conversions (homogeneous) have been well documented, heterogeneous phase reactions are less well understood. A combination of theoretical predictions, basic laboratory studies, and field investigations support conclusions that heterogeneous reactions are probably important atmospheric chemical processes. One objective of this work is to improve the capabilities for studying heterogeneous chemical transformations in the atmosphere. This research project may lead to new concepts in chemical reactivity in atmospheric systems. The specific objectives for this project are to: (1) develop improved understandings of atmospheric heterogeneous chemical reactions; and (2) determine trends, patterns and behavior of chemical reactions between gases and complex atmospheric aerosols.
