Development of a System for In Situ Monitoring of Volatile Organics

9424211伦纳德奖是一个奖项，旨在支持在检测水中有机污染物的存在和性质的系统中潜在使用远程光纤光谱分析的研究。这项研究是在先前工作的基础上进行的，该工作导致了一种新型的光学电极的开发，该光学电极利用荧光指示剂来检测和监测水溶液中的纯极性有机物。即将进行的研究涉及一种技术，即通过光纤将适当波长的光发射到远程样本。样品的返回信号被样品的化学性质改变，以揭示化学物质的确切性质或其所属的化学基团。检测渗入含水层的有机物质的存在和浓度是修复被危险物质污染的土壤和含水层的重要步骤。预计这项研究的结果将成为整个遥感研究的重要一环，部分原因是它将侧重于实用方面，如坚固性、光电极寿命和低浓度研究。基于此的未来仪器有可能极大地减少安全风险，减少工作时间，并产生关于受污染环境资源的环境质量的实时化学数据。***

9424211 Leonard This is an award to support research on the potential use of remote fiber spectroscopy in a system to detect the presence and nature of organic contaminants in water. This research is based on prior work that led to development of a novel optrode that utilized a fluorescent indicator to detect and monitor pure polar organic substances in water solution. The research to be conducted involves a technique in which light of an appropriate wave length is launched through an optical fiber to a remote sample. The return signal from the sample is changed by the sample's chemical properties to reveal either the exact nature of the chemical or the chemical group to which it belongs. Detection of the presence and concentrations of organic substances that leak into aquifers is an important step in remediation of soils and aquifers contaminated by hazardous substances. Results of this research are expected to be an important link in overall remote sensing research partly because it will focus on practical aspects such as ruggedness, optrode lifetime and low concentration studies. Future instrumentation based on this consist has the potential of greatly reducing safety hazards, person hours and produce real-time chemical data on environmental quality of contaminated environmental resources. ***
