The purpose of this research is to identify and quantify the metal species that exist as a result of thermal degradation of hazardous waste. To realize this objective three task have been formulated: 1) to review the literature for analytical methods which have been applied to the determination of metal species 2) to apply existing methods or develop new methods to analyze for metal species in samples obtained from a controlled combustion environment, and 3) to modify or develop and test metal species sampling systems To this end, analytical methods using the currently available techniques of ion chromatography and X-ray diffraction to identify and quantify the metal species found in the gas phase of an experimental reactor will be developed, along with a sampling system for metal species. Future research will determine the effect of combustion parameters (e.g. temperature, chemical makeup, and residence time) on the metal species formed. Knowledge of the actual species will be utilized to develop an algorithm to predict the fate of the metal constituents during rotary-kiln incineration.

本研究的目的是识别和量化 由于热降解而存在的金属物质 危险废物。 为实现这一目标， 已制定： 1)审查分析方法的文献， 有 应用于金属离子的测定 物种 2)应用现有方法或开发新方法， 分析从一个实验室获得的样品中的金属物质 受控的燃烧环境，以及 3)修改或开发和测试金属种类取样 系统 为此，分析方法使用目前可用的 离子色谱和X射线衍射技术， 确定和量化气相中发现的金属物质 将开发一个实验反应堆，沿着 金属种类的取样系统。 未来的研究将确定燃烧的效果 参数（例如温度、化学组成和停留时间 时间）对所形成的金属物质的影响。 实际知识 物种将被用来开发一种算法来预测 金属成分在回转窑中的归宿 焚化
