Abstract Schofield CTS-9503660 The PI proposes to investigate the combustion chemistries of As, Sb, Se, and Hg, four toxic metals, whose presence can be of concern in coal combustion and incinerator effluents. From the measured profiles of the atoms, oxides, and chlorides of these metals obtained from seeded H2/O2/N2 or H2/O2/Ar flat premixed flames using laser induced fluorescence and emission spectroscopic techniques, he plans to deduce their distributions and those of other possible unidentified species containing these metals as a function of temperature. This information can lead to relevant thermochemical data such as bond energies and heats of formation for these species fop which no reliable data presently exists and to mechanistic insights involving the kinetics of these species.

摘要斯科菲尔德CTS-9503660 PI建议研究As、Sb、Se和Hg（四种有毒金属）的燃烧化学，这些金属的存在可能会引起燃煤和焚烧炉排出物的关注。从测量的配置文件的原子，氧化物，和氯化物的这些金属从种子H2/O2/N2或H2/O2/Ar平面预混火焰使用激光诱导荧光和发射光谱技术，他计划推断它们的分布和其他可能的身份不明的物种包含这些金属作为温度的函数。这些信息可以导致相关的热化学数据，如键能和这些物种的生成热，目前还没有可靠的数据，并涉及这些物种的动力学的机械见解。
