This SBIR Phase I project will develop an advanced state-of-the-art perchlorate remediation technology by using magnetic nanoparticles functionalized with selective perchlorate ion-receptors. Ion exchange, which is the most widely used technology for treating water containing less than 100ppb of perchlorate, has the drawback of needing frequest regeneration or disposal of the perchlorate-laden resins. This project will investigate the feasibility of using functionalized magnetic nanoparticles with certain specific anion receptors to selectively bind CIO4. The broader/commercial impacts of the proposed project will be the removal of perchlorate contamination from drinking water sources. EPA estimates that about 90% of the perchlorate manufactured in the U.S. is used by the military or NASA. Perchlorate contamination has been detected in over 350 drinking water sources in California alone. Perchlorate cleanup in the U.S. is estimated to cost over $300 million. A cost-effective and environmentally acceptable technology could focus on some market share of the estimated $60 million market for perchlorate removal.

该SBIR一期项目将开发一种先进的、最先进的高氯酸盐修复技术，该技术使用具有选择性高氯酸盐离子受体功能化的磁性纳米颗粒。离子交换是处理高氯酸盐含量低于100ppb的水的最广泛使用的技术，其缺点是需要频繁地再生或处理含高氯酸盐的树脂。本项目将研究功能化磁性纳米颗粒与特定阴离子受体选择性结合CIO4的可行性。拟议项目的更广泛/商业影响将是消除饮用水源中的高氯酸盐污染。美国环保署估计，美国生产的高氯酸盐约有90%被军方或美国国家航空航天局（NASA）使用。仅在加州就有350多个饮用水源被检测出高氯酸盐污染。据估计，美国的高氯酸盐清理费用超过3亿美元。一项具有成本效益和环境可接受的技术可以集中在高氯酸盐去除市场中约6000万美元的部分市场份额上。
