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.

该项目由Paul Flowers博士和位于彭布罗克的北卡罗来纳州大学的本科生进行，得到了分析和表面化学项目的支持。该研究是NSF本科院校研究（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，可用于各种原位测量。具体的研究内容包括：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价; 2）所选分析物的光谱和氧化还原性质的表征; G. Cu（II）和Cr（VI）在各种溶液中的浓度; 3）开发和评估FOSEC传感器测量这些分析物的分析方案。 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，并增加多功能性。
