摘要提案标题：SGER过氧化物基炸药电化学检测提案编号：CBET-0707038主要研究者：I。F Cheng，机构：莎士比亚大学从知识价值的角度来看，迫切需要能够定量和定性检测过氧化物基爆炸物的方法和技术。这种奋进的基本化学尚未完全描述。本研究将探讨电化学调解的芬顿反应作为检测这类爆炸物的基础。由于均相芬顿反应和Fe III络合物电还原为Fe II，发生了介导。FeIIcomplex + RO-或FeIIComplex + RO- + RO..由于Fe III络合物的电还原而产生的电流与过氧化物浓度的平方根成比例。预计该过程将是快速，稳健和廉价的。拟议的研究将检查检测限、动力学以及该铁复合物螯合物的作用。后者是基于循环伏安法研究开发的结构-活性关系的考虑。这项探索性研究小额资助（SGER）旨在证明这种检测过氧化物基爆炸物的新方法可以利用，并将产生更广泛的影响。如果成功，PI预计该SGER提案将导致更详细的EXP提案，其中将在精心设计的实验和教学计划中进一步探索和表征基于Fentons试剂的系统，此外，PI可能会从其他政府机构以及其他NSF计划元素中寻求进一步的资金。

Abstract Proposal Title: SGER Electrochemical Detection of Peroxide-Based Explosives Proposal Number: CBET-0707038 Principal Investigator: I. F Cheng, Institution: University of IdahoFrom an Intellectual Merit perspective, there is an urgent need for methods and techniques that are able to detect quantitatively and qualitatively peroxide based explosives. The basic chemistries for such endeavor have not been fully described. This investigation will examine the electrochemical mediation of the Fenton Reaction as a basis for detection of this class of explosives. The mediation takes place as a result of the homogeneous Fenton Reaction and the electro-reduction of an FeIII complex to FeII. FeIIcomplex + RO-OR FeIIIcomplex + RO- + RO.. The current due to the electro-reduction of the FeIII complex is proportional to the square root of the peroxide concentration. The process is expected to be rapid, robust, and inexpensive. The proposed study will examine the detection limits, kinetics and the role of the chelate of that iron complex. The latter is based on considerations of the structure-activity relationships developed by cyclic voltammetric studies.This Small Grant for Exploratory Research (SGER) seeks to prove that this novel approach to detection of peroxide based explosives can be utilized and will have Broader Impacts. If successful, the PI anticipates that this SGER proposal will lead to a more detailed EXP proposal where the Fentons Reagent-based system will be further explored and characterized within a carefully crafted experimental and teaching plan, additionally the PI may seek further funding for these concepts from other government agencies as well as other NSF program elements.
