U.S.- Hungary Chemistry Research on Mechanism of the Reaction of Iron - Ethylenediaminetetraacetate (EDTA) and Related Complexes with Hydrogen Peroxide

这个由佛罗里达理工学院的Virender Sharma和布达佩斯的Eotvos Lorand大学的Zoltan Homonnay合作的美国-匈牙利研究项目的目标是研究乙二胺四乙酸酯（EDTA）和相关的铁配合物在水介质中与过氧化氢的反应。铁与EDTA结合强烈，过氧化氢作为氧化剂参与了许多生物、工业和环境化学反应。美国和匈牙利的研究团队计划通过使用穆斯堡尔光谱技术识别反应中铁和含铁络合物的氧化态，并通过研究反应的动力学和氧化产物的特征来研究这种反应机制。研究结果将提高我们对Fenton反应和其他涉及铁配合物的反应的认识。由于铁和铁的形态在生物系统中很重要，对水生系统中铁和铁化学的详细了解可以在无机化学和物理化学方面取得根本性的进展，在绿色合成、环境化学和一般氧化还原反应中具有潜在的应用。该合作化学项目实现了推进科学知识的计划目标，使美国和中欧的专家能够结合互补的人才，并在共同感兴趣和有能力的领域共享研究资源。更广泛的影响包括通过在匈牙利合作伙伴机构的工作，将一名美国研究生引入国际研究界，并直接参与该项目对穆斯堡尔光谱技术的新应用。

The goal of this U.S.-Hungarian research project between Virender Sharma of Florida Institute of Technology and Zoltan Homonnay of Eotvos Lorand University in Budapest is to investigate the reaction of ethylenediaminetetraacetate (EDTA) and related complexes of iron with hydrogen peroxide in an aqueous medium. Iron binds strongly with EDTA, and hydrogen peroxide as an oxidant is involved in numerous biological, industrial and environmental chemical reactions. The team of U.S. and Hungarian researchers plans to study this reaction mechanism by identifying oxidation states of iron and iron-containing complexes in the reaction using Mossbauer spectroscopic techniques and by studying the kinetics and the characteristics of oxidation products from the reaction. Results should improve our understanding of the Fenton reaction, and other reactions involving iron complexes. Since iron and iron speciation is important in biological systems, a detailed understanding of iron and iron chemistry in aquatic systems could produce fundamental advancements in inorganic chemistry and physical chemistry that have potential applications in green synthesis, environmental chemistry, and general redox reactions. This collaborative chemistry project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include the introduction of a U.S. graduate student to the international research community through work at the Hungarian partner's institution and direct involvement in the project's novel application of Mossbauer spectroscopic techniques.
