This Research Planning Grant is supported by the Analytical and Surface Chemistry Program. Professor Zoski is spending a sabbatical initiating a collaboration with Professor Dana R. Kester of the Graduate School of Oceanography at the Narragansett Bay Campus of the University of Rhode Island. During this time she is learning the special requirements of doing analytical chemistry in a marine environment together with her students. This project will focus on fabricating microelectrodes and microsensors and characterizing their function under real marine environmental conditions. These electrodes will be compared with commercially available sensors for analytes such as oxygen that employ membranes to protect against fouling. The behavior of bare metal microelectrodes in marine samples will be characterized using a sequence of applied potential pulses designed to clean and activate the metal surface and then analyze for specific analytes. The course of this applied work will be guided by fundamental theoretical work, the PI's area of expertise, throughout this project. This work focusses on the development of microelectrodes and microsensors that can be used in the complex matrices found in marine aquatic samples. Theoretical and experimental work will be used together to characterize the analytical responses of these electroanalytical probes so that robust, real-time systems can be developed and used for marine chemical analysis. Professor Zoski and her students at the University of Rhode Island will begin a collaboration with Professor Kester at the university's Graduate School of Oceanography that will result in more reliable analytical information about the chemistry of marine environments.

这项研究计划补助金由分析和表面化学计划支持。 Zoski教授正在休假，与Dana R.罗得岛大学纳拉甘塞特湾校区海洋学研究生院的凯斯特说。 在此期间，她正在学习在海洋环境中与学生一起进行分析化学的特殊要求。 该项目将侧重于制作微电极和微传感器，并说明它们在真实的海洋环境条件下的功能。 这些电极将与市售的分析物传感器进行比较，如采用膜来防止污染的氧气。 海洋样品中裸金属微电极的行为将使用一系列施加的电位脉冲进行表征，这些脉冲旨在清洁和激活金属表面，然后分析特定的分析物。 这项应用工作的过程中，将指导基础理论工作，PI的专业领域，在整个项目。 这项工作的重点是微电极和微传感器，可用于在海洋水生样品中发现的复杂矩阵的发展。 理论和实验工作将一起用来描述这些电分析探针的分析反应，以便开发可靠的实时系统并用于海洋化学分析。 Zoski教授和她在罗得岛大学的学生将开始与该大学海洋学研究生院的Kester教授合作，这将导致有关海洋环境化学的更可靠的分析信息。
