Gas-Solid Phase Reactions of Organic Compounds on Fly Ash

这项研究的目的是更好地了解大气中与空气中颗粒物相互作用的化合物的化学转化和环境命运。虽然许多气态化学转化(均相)已经被很好地记录下来，但对非均相反应的了解较少。理论预测、基础实验室研究和现场调查相结合，支持多相反应可能是重要的大气化学过程的结论。这项工作的目标之一是提高研究大气中非均相化学变化的能力。这一研究项目可能导致大气体系中化学反应的新概念。该项目的具体目标是：(1)增进对大气非均相化学反应的了解；(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.
