The broader impacts of this Small Business Innovation Research Phase I project are to create a method for the degradation of per- and polyfluoroalkyl substances (PFAS) – often called “forever” chemicals - in water. PFAS contamination is a significant global problem, and it is estimated that 97% of US citizens have PFAS in their blood. The resultant human and animal health implications include immunological, reproductive, developmental, hepatic, hormonal, and carcinogenic diseases. Currently, the removal of PFAS in drinking water resources is a major focus of the federal government and among many state governments. However, the cost, intensive maintenance, and complexity of available advanced water treatment technologies have often made their adoption out of reach. While these harmful PFAS are difficult to destroy, the proposed novel process transforms them into harmless byproducts. This project has the potential to treat PFAS-contaminated water with lower energy costs and faster removal rates, which could be broadly useful to affected communities throughout the country. The approach integrates advanced processes without extensive energy requirements and without the need for chemical use and post-processing. This technology is expected to be affordable, scalable, and easy to operate and maintain on-site.This SBIR Phase I project proposes to design and implement a novel cathodic treatment system for the removal of per- and polyfluoroalkyl substances (PFAS) from groundwater. The unique design proposes to employ both reductive and oxidative cathodes for PFAS removal. The project aims to research, design, and test an electrochemical cell prototype with novel electrode materials that support electrochemically-induced reduction and oxidation processes. Tasks include testing the electrode substrates and catalyst-coating materials and optimizing the operational parameters relative to rapid breaking of C-F bonds and low-energy consumption. The project will develop a robust electrochemical device that operates under environmentally relevant concentrations of PFAS and other co-contaminants, such as natural organic matter and chlorinated volatile organics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究第一阶段项目的更广泛影响是创造一种方法来降解水中的全氟烷基和多氟烷基物质（PFAS）-通常被称为“永久”化学品。PFAS污染是一个严重的全球性问题，据估计，97%的美国公民血液中含有PFAS。由此产生的人类和动物健康影响包括免疫、生殖、发育、肝脏、激素和致癌性疾病。目前，去除饮用水资源中的PFAS是联邦政府和许多州政府的主要焦点。然而，现有的先进水处理技术的成本、密集的维护和复杂性往往使它们的采用遥不可及。虽然这些有害的PFAS很难破坏，但拟议的新工艺将它们转化为无害的副产品。该项目有可能以更低的能源成本和更快的去除率处理PFAS污染的水，这可能对全国受影响的社区广泛有用。该方法集成了先进的工艺，没有广泛的能源需求，也不需要化学品的使用和后处理。这项技术预计将是负担得起的，可扩展的，易于操作和维护的现场。这个SBIR第一阶段项目提出设计和实施一种新型的阴极处理系统，用于去除地下水中的全氟和多氟烷基物质（PFAS）。独特的设计建议采用还原性和氧化性阴极来去除PFAS。该项目旨在研究，设计和测试具有新型电极材料的电化学电池原型，这些材料支持电化学诱导的还原和氧化过程。任务包括测试电极基底和催化剂涂层材料，并优化与C-F键的快速断裂和低能耗相关的操作参数。该项目将开发一个强大的电化学装置，在PFAS和其他共污染物的环境相关浓度下运行，如天然有机物和氯化挥发性有机物。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
