项目摘要
With support from the Chemical Measurement and Imaging Program in the Chemistry Division, Profs. Eric Conte and Stuart Burris and their groups at Western Kentucky University are studying the chemistry affecting electrically-controlled adsorption of surfactants on various conductive metal surfaces. Under conditions when the surfactant is held onto the conductive surface, the system will be devised to serve as an alternative approach to preconcentration for organic substances, whereby the surfactant acts as an adsorbing phase. The surfactant, together with the trapped material, will then be released by changing the electric field. If release by electrical control proves efficient, the organic solvents used in conventional preconcentration procedures will not be required, making this procedure environmentally advantageous. This is an intrinsically "green" chemistry program, in the sense that it may provide an effective way to reduce the use of toxic solvents. The work has additional impact in that it entails multidisciplinary training for Masters and undergraduate students, particularly those from underrepresented groups (minorities and Appalachia) in Kentucky. Students will gain valuable hands-on experience in Electrochemical Impedance Spectroscopy, Atomic Force Microscopy and High Performance Liquid Chromatography. The work is synergistic with Dr. Conte's Taiwanese student exchange and collaboration, supported separately by the Office of International Science and Engineering.
在化学部化学测量和成像计划的支持下,教授。西肯塔基大学的埃里克·孔特和斯图尔特·伯里斯及其团队正在研究影响表面活性剂在各种导电金属表面上电控制吸附的化学。在表面活性剂被保持在导电表面上的条件下,该体系将被设计为一种替代的有机物质预浓缩方法,由此表面活性剂充当吸附相。然后,通过改变电场,表面活性剂和被捕获的物质将被释放。如果通过电控释放被证明是有效的,则不需要使用常规预浓缩程序中使用的有机溶剂,从而使该程序对环境有利。这是一个本质上“绿色”的化学项目,从某种意义上说,它可能提供了一种减少有毒溶剂使用的有效方法。这项工作具有额外的影响,因为它需要对硕士和本科生进行多学科培训,特别是那些来自肯塔基州代表性不足的群体(少数民族和阿巴拉契亚地区)的学生。学生将在电化学阻抗光谱学、原子力显微镜和高效液相色谱仪方面获得宝贵的实践经验。这项工作是与孔戴博士的台湾学生交换和合作项目协同进行的,该项目由国际科学与工程办公室单独支持。
