U.S.-Germany Cooperative Research: An Integrated Analytical Approach for the Structural Characterization and Proton Binding of Size-Fractionated Natural Organic Matter

0129516 Perdue这个奖项支持迈克尔·珀杜和学生从格鲁吉亚技术在化学系的安东尼厄斯·凯特鲁普在慕尼黑，德国工业大学的合作。 该国际项目的目的是描述天然有机物中分子量的分布和取决于pH值的电荷分布，天然有机物是一种高度复杂的酸性混合物，在天然沃茨中随处可见。 本项目将以美国格鲁吉亚州苏瓦尼河的天然有机物样品为研究对象，该样品可从国际腐殖物质协会获得，并将结合毛细管电泳和电位滴定的实验结果，以阐明物质中电荷的实际分布。拟议中的研究有很大的潜力，以提高我们的能力，以处理当代重要的问题，如环境毒理学的金属和有机化学品和dthe影响流域性质对水生系统。 工作计划规定研究生广泛参与国际旅行和研究。

0129516PerdueThis award supports Michael Perdue and students from Georgia Tech in a collaboration with Antonius Kettrup of the Department of Chemistry at the Technical University of Munich, Germany. The aim of the international project is to describe the distribution of molecular weight and the pH-dependent distribution of charge in natural organic matter, which is a highly complex acidic mixture that occurs everywhere in natural waters. This project will focus on a sample of natural organic matter from the Suwannee River, Georgia, USA, which is available from the International Humic Substance Society, and will integrate experimental results from capillary electrophoresis and potentiometric titration to elucidate the actual distribution of charge in the matter. The proposed research has a high potential to advance our ability to deal with important contemporary problems such as environmental toxicology of metals and organic chemicals an dthe influences of watershed properties on aquatic systems. The work plan provides for extensive participation by graduate students in the international travel and research.
