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

美国的目标是-匈牙利佛罗里达理工学院的Virender Sharma和布达佩斯的Eotvos Lorand大学的Zoltan Homonnay的研究项目是研究乙二胺四乙酸盐（EDTA）和相关的铁与过氧化氢的络合物在水介质中的反应。 铁与EDTA强烈结合，过氧化氢作为氧化剂参与许多生物，工业和环境化学反应。 美国和匈牙利的研究人员计划通过使用穆斯堡尔光谱技术确定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性来研究这种反应机制。 这些结果将提高我们对芬顿反应和其他涉及铁络合物的反应的理解。 由于铁和铁的形态在生物系统中是重要的，铁和铁化学在水生系统中的详细了解可以产生在无机化学和物理化学，在绿色合成，环境化学和一般的氧化还原反应具有潜在的应用的根本性的进步。这个合作化学项目通过使美国和中欧的专家能够联合收割机互补人才，并在共同感兴趣和能力强的领域共享研究资源，实现了推进科学知识的计划目标。更广泛的影响包括通过在匈牙利合作伙伴的机构工作，将一名美国研究生介绍给国际研究界，并直接参与该项目的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.
