Fiber Optic Spectroelectrochemical Sensors for In Situ Measurements

该项目由Paul Flowers博士和北卡罗来纳大学彭布罗克分校的本科生共同完成，并得到了分析和表面化学项目的支持。这项研究是美国国家科学基金会本科生研究所(RUI)计划的一部分，开发了光纤光谱电化学(FOSEC)传感器和相关方法，可用于各种现场测量。具体地说，这项研究包括1)构建和评估用于吸光度和荧光测量的光纤光谱电化学传感器，2)表征选定的分析物，例如铜(II)和铬(VI)在各种溶液中的光谱和氧化还原性质，以及3)开发和评估用于FOSEC传感器测量这些分析物的分析方案。这项研究有望带来新的现场测量策略。与它们所取代的分析方法相比，这种策略可以提高选择性，减少化学浪费，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.
