This Small Business Innovation Research (SBIR) Phase I project addresses the analysis needs for monitoring perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in waste water. Perfluorochemicals (PFCs) are bio-accumulative, extremely persistent and toxic; and there is a huge effort surrounding remediation of PFOA and PFOS contaminated areas. Considering the impacts on environment and public health, it is important to monitor PFOA and PFOS. Although there are established LC/MS/MS methods to measure them at low levels, this equipment is expensive and not generally field portable. This research aims at the development of a field and lab deployable ion-selective electrode that permits selective and fast measurement of PFOA and PFOS with a low detection limit at low cost. The project will take advantage of the highly selective and fouling-resistant fluorous membranes recently licensed from the University of Minnesota. The broader impacts of this research are significant as the proposed sensor will provide a fast, easy, sample pretreatment free, selective and economical detection method for environmental monitoring, compliance and remediation efforts, which are currently hampered by costly and time consuming liquid extractions coupled with LC/MS. Additional broader impacts include expanded application of the sensor to measure the contaminant in blood, soil and food. Most importantly, these efforts are important and instructive to direct and monitor remediation and enable in-field research. We view this effort as an integral part of a wider effort to understand and reduce sources and pathways by which the persistent substance has become widespread in the environment.

该小型企业创新研究 (SBIR) 第一阶段项目解决了监测废水中全氟辛酸 (PFOA) 和全氟辛烷磺酸 (PFOS) 的分析需求。全氟化合物 (PFC) 具有生物累积性、极持久性和毒性；人们为修复 PFOA 和 PFOS 污染区域付出了巨大的努力。考虑到对环境和公众健康的影响，监测 PFOA 和 PFOS 非常重要。尽管已经建立了 LC/MS/MS 方法来测量低浓度的它们，但该设备价格昂贵且通常不便于现场携带。本研究旨在开发一种现场和实验室可部署离子选择性电极，能够以较低的检测限和较低的成本选择性、快速地测量 PFOA 和 PFOS。该项目将利用明尼苏达大学最近获得许可的高选择性和防污氟膜。 这项研究的广泛影响是重大的，因为所提出的传感器将为环境监测、合规性和补救工作提供一种快速、简单、无需样品预处理、选择性和经济的检测方法，而目前这些方法受到昂贵且耗时的液体萃取与 LC/MS 相结合的阻碍。其他更广泛的影响包括传感器的扩展应用，以测量血液、土壤和食物中的污染物。最重要的是，这些努力对于指导和监测补救措施以及开展现场研究非常重要且具有指导意义。我们认为这项努力是了解和减少持久性物质在环境中广泛传播的来源和途径的更广泛努力的一个组成部分。
