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

该奖项支持Michael Perdue和佐治亚理工学院的学生与德国慕尼黑工业大学化学系的Antonius Kettrup合作。这个国际项目的目的是描述天然有机物质中分子量的分布和电荷的ph依赖分布，天然有机物质是一种高度复杂的酸性混合物，在自然水域中随处可见。本项目将重点研究来自美国乔治亚州苏旺尼河的天然有机物质样本，该样本可从国际腐殖质学会获得，并将综合毛细管电泳和电位滴定的实验结果来阐明物质中电荷的实际分布。该研究对我们处理诸如金属和有机化学品的环境毒理学以及流域特性对水生系统的影响等重要当代问题的能力有很大的潜力。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.
