U.S.-Germany Cooperative Research: Characterization of Arsenic-Containing Compounds in Soils and Groundwater

该奖项支持Carol Haney博士、Dale Sayers博士、Dean Hester berg博士和北卡罗来纳州立大学的一名研究生与罗斯托克大学自动化工程系的Norbert Stoll合作。这项合作将德国和美国两个集团的互补能力结合在一起，开发出提取、制备和分析含砷土壤和水样的方法。这些样本将从德国东部的一个二战化学武器制造基地收集。初步迹象表明，该地点受到有机和无机砷化合物的严重污染。这项研究的目标是对现场的含砷化合物进行完整的表征，确定有机砷化合物在不同地点和土壤类型中转化为无机化合物的机制，并开发修复技术。分析方法有气相色谱、高压液相色谱/质谱仪和X射线吸收光谱分析。

This award supports Drs. Carol Haney, Dale Sayers, Dean Hesterberg and a graduate student from the North Carolina State University in a collaboration with Norbert Stoll of the Department of Automation Engineering at the University of Rostock. The collaboration brings together the complementary capabilities of the German and U.S. groups to develop methods for the extraction, preparation, and analysis of soil and water samples containing arsenic. The samples will be collected from a World War II chemical weapons manufacture site in the eastern part of Germany. Preliminary indications are that the site has significant contamination from both organic and inorganic arsenic compounds. The goals of the research are a complete characterization of the arsenic-containing compounds at the site, determination of the mechanisms by which organic arsenic compounds are transformed into inorganic compounds in different locations and soil types, and development of remediation techniques. Analytical methods to be used are gas chromatography, high-pressure liquid chromatography/mass spectrometry, and x-ray absorption spectroscopy.
