ABSTRACTOCE-0081073In this project, the principal investigators and his associates at the University of Miami will continue their ongoing research into the physical chemistry of iron and other dissolved substances in seawater. They will especially concentrate on determining the solubility in seawater of the very important iron species ferric hydroxide -- believed to be of great importance in the regulation of bioavailable iron. This work will also include an examination of the effects of natural organic ligands that can bind iron and this impact its chemical reactivity, solubility, and availability for utilization by marine organisms. This work with iron will be a continuation of this investigator's longstanding basic research program into ionic interactions in seawater and the implications for chemical speciation, thermodynamic processes, and the rates of chemical reactions in seawater.

ABSTRACTOCE-0081073 在这个项目中，迈阿密大学的主要研究人员和他的同事将继续他们对海水中铁和其他溶解物质的物理化学的持续研究。 他们将特别专注于确定非常重要的铁物质氢氧化铁在海水中的溶解度，据信氢氧化铁对于生物可利用铁的调节非常重要。 这项工作还将包括检查可以结合铁的天然有机配体的影响，这会影响其化学反应性、溶解度和海洋生物利用的可用性。 这项关于铁的工作将是该研究人员长期基础研究计划的延续，该研究计划涉及海水中的离子相互作用及其对化学形态、热力学过程和海水中化学反应速率的影响。
