Fiber Optic Spectroelectrochemical Sensors for In Situ Measurements

该项目由北卡罗来纳大学彭布罗克分校的Paul Flowers博士和本科生进行，得到了分析和表面化学项目的支持。该研究是美国国家科学基金会本科院校研究（RUI）计划的一部分，旨在开发光纤光谱电化学（FOSEC）传感器和相关方法，以潜在地应用于各种原位测量。具体而言，研究包括1)用于吸光度和荧光测量的光纤光谱电化学传感器的构建和评估，2)选定分析物（例如Cu（II）和Cr(VI)）在各种溶液中的光谱和氧化还原特性的表征，以及3)开发和评估用于这些分析物的FOSEC传感器测量的分析方案。这项研究有望导致新的原位测量策略。与它们所取代的分析方法相比，这种策略可以提高选择性，减少化学废物，并增加通用性。

This project, conducted by Dr. Paul Flowers and undergraduate students at the University of North Carolina at Pembroke, is supported in the Analytical and Surface Chemistry program. The research, which is a part of NSF's Research in Undergraduate Institutions (RUI) initiative, develops fiber optic spectroelectrochemical (FOSEC) sensors and related methodology for potential application to various in situ measurements. Specifically the research includes 1) construction and evaluation of the fiber optic spectroelectrochemical sensors for absorbance and fluorescence measurements, 2) characterization of the spectroscopic and redox properties of selected analytes, e. g. Cu(II) and Cr(VI) in various solutions , and 3) development and assessment of analytical protocols for FOSEC sensor measurement of these analytes. This research is expected to lead to new in situ measurement strategies. Such strategies could result in enhanced selectivities, reduced chemical waste, and increased versatility when compared to the analytical methods that they replace.
