RUI: An Innovative Hybrid Technology for the Removal and Destruction of Perchlorate from Aqueous Systems Using Polymeric Ligand Exchange Technology and a Packed Bed Bio-Reactor

摘要：利用聚合物配体交换技术和填充床生物反应器去除和破坏水系统中高氯酸盐的创新混合技术地下水中的高氯酸盐（ClO 4-）污染是美国许多地区和世界各地的一个重要环境问题。因此，高氯酸盐自1998年以来一直在美国环境保护署污染物候选名单上。人类摄入高氯酸盐会抑制碘的吸收，从而影响甲状腺的功能。由于甲状腺在人类发育中的作用，高氯酸盐消费对儿童和孕妇的影响可能特别严重。由于高氯酸盐的不挥发性、高溶解性和动力学惰性，用常规技术修复受污染的地下水是低效的。目前的研究探索了许多新的修复技术，离子交换似乎是最有前途的方法。一个有效的，创新的，经济上可行的程序，从污染的地下水中分离高氯酸盐与环境友好的过程，其破坏将被开发。该研究将为开发和使用新型高分子配体交换剂分离高氯酸盐提供重要的新信息。本项目还将重点关注（1）促进教学、培训和学习：每个PI都有不同学科的任命，每个PI都将通过自己的专业知识为项目的成功做出贡献。拉斐特学院的学生，其中许多人追求环境科学，政策和管理的职业生涯，渴望获得化学，工程，生物学和环境科学研究的基本原理的理解。本研究为这一群体的教学和培训提供了一个理想的多学科机会。来自不同专业的学生将参加这项研究。(2)扩大代表性不足群体的参与：在帮助进行初步研究的五名本科生中，有三名是女性;我们预计，由于其环境重点，该项目将吸引女学生。(3)对社会的益处：饮用水中的高氯酸盐污染是一个全球性的问题，开发一种经济有效的去除高氯酸盐的方法对公众福利具有相当重要的意义。

ABSTRACTRUI: An innovative Hybrid Technology for the Removal and Destruction of Perchlorate from Aqueous Systems Using Polymeric Ligand Exchange Technology and a Packed Bed Bio-ReactorPerchlorate, ClO4-, contamination in groundwater is a significant environmental concernin many regions of the United States and throughout the world. For this reason, perchlorate has been on the U.S. Environmental Protection Agency Contaminate Candidate List since 1998. Human consumption of perchlorate is known to affect the function of the thyroid gland by inhibiting the uptake of iodide. The affects of perchlorate consumption on children and pregnant women can be especially severe because of the role that the thyroid plays in human development. Because of its nonvolatile, highly soluble, and kinetically inert nature, perchlorate remediation of contaminated groundwater by conventional techniques is inefficient. Current research explores many new remediation technologies, with ion-exchange seemingly the most promising method.An efficient, innovative, and economically-feasible procedure for the separation of perchlorate from contaminated groundwater coupled with an environmentally benign process for its destruction will be developed. The study will contribute significant new information for the development and use of a new class of polymeric ligand exchangers for perchlorate separation.This project will also focus upon (1) Promoting Teaching, Training and Learning: Each of the PIs has an appointment in a different discipline, and each will contribute to this projects success through his/her own expertise. Lafayette College students, many of whom pursue careers in environmental science, policy, and management, are eager to obtain an understanding of the fundamental principles of research in chemistry, engineering, biology, and environmental science. This research provides an ideal multidisciplinary opportunity for teaching and training this group. Students from many different majors will take part in this research. (2) Broadening Participation of Underrepresented Groups: Among the five undergraduates who have helped produce the preliminary research, three are women; we anticipate that, because of its environmental focus, this project will appeal to female students. (3) Benefits to society: Perchlorate contamination in drinking water is a global problem and the development of a cost effective means of its removal is of considerable importance to public welfare.
