中文摘要
9529448扎菲里奥本项目的中心目标将是研究在阳光充足的海洋水域中超氧化物(一种光化学形式的氧)的化学以及铜和铁的化学形态之间的氧化-还原相互作用的动力学。首席研究人员还将检验一种新的假设,即这两种金属存在氧化和还原的溶解物种。这项研究应该会对光化学反应在影响上层海洋氧化还原敏感痕量金属形态方面所起的作用产生重要的新见解。
英文摘要
9529448 Zafiriou The central objective of this project will be to study the kinetics of oxidation-reduction interactions coupling the chemistry of superoxide (a photochemically induced form of oxygen) and copper and iron chemical speciation in sunlit marine waters. The principal investigator will also test a new hypothesis which suggests that there is oxidized and reduced dissolved species of these two metals. This research should lead to important new insights on the role played by photochemical reactions in influencing the speciation of redox-sensitive trace metals in the upper ocean.
