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 第一阶段项目将通过使用具有选择性高氯酸盐离子受体功能的磁性纳米颗粒来开发先进的最先进的高氯酸盐修复技术。 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，其缺点是需要频繁再生或处理含有高氯酸盐的树脂。 该项目将研究使用功能化磁性纳米颗粒与某些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。 EPA 估计，美国生产的高氯酸盐中约 90% 供军方或 NASA 使用。 仅在加利福尼亚州，就有 350 多个饮用水源检测到高氯酸盐污染。 美国的高氯酸盐清理费用估计超过 3 亿美元。 一项具有成本效益且环境可接受的技术可以专注于在估计价值 6000 万美元的高氯酸盐去除市场中占据部分市场份额。
