This Small Business Innovation Research (SBIR) Phase I project addresses the global contamination issues of per- and poly-fluoroalkyl substances (PFAS) – also known as “forever chemicals” – in drinking water resources. The technology aims to develop a proof-of-concept, cost-effective technology that destroys PFAS chemicals even at very low levels and converts them to non-toxic. benign products in an ambient environment. Ultimately, the project team aims to provide improved water sustainability and safeguard public health. The project is aligned with the American Innovation and Competitiveness Act by advancing of the health and welfare of the American public. Initial demonstration of these impacts is expected to be felt in the water-scarce and economically fast-growing inland southern California region for both centralized and decentralized water treatment. This effort focusses on the development of a highly efficient and cost-effective photochemical treatment system for the destruction of PFAS in drinking water resources. Using a novel tunable deep ultraviolet light (a.k.a. vacuum ultraviolet or VUV), the technology aims to achieve nearly complete destruction of PFAS without generating secondary waste streams or toxic byproducts in drinking water. VUV light is one of the most accessible and efficient water ionization photon sources because it takes advantage of abundant water molecules as photon sensitizers, can be readily generated from common UV lamps, and is easy to control and operate. Tuning this light source in conjunction with other benign chemicals creates a highly reactive environment for efficient destruction of PFAS, converting waterborne PFAS into non-toxic fluoride. The effort will involve combination of chemical kinetics investigation, advanced chemical analysis, and technology scale-up in collaboration with potential customers.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.

该小型企业创新研究 (SBIR) 第一阶段项目旨在解决饮用水资源中全氟烷基物质和多氟烷基物质 (PFAS)（也称为“永久化学品”）的全球污染问题。 -概念性的、具有成本效益的技术，即使在非常低的水平下也能破坏 PFAS 化学品，并将其转化为周围环境中的无毒产品。该项目的最终目标是提高水的可持续性并保障公众健康。与《美国创新与竞争力法案》通过促进美国公众的健康和福利，预计这些影响将在缺水且经济快速增长的南加州内陆地区感受到，无论是集中式还是分散式水处理。这项工作的重点是开发一种高效且具有成本效益的光化学处理系统，利用新型可调谐深紫外光（又称真空紫外光或真空紫外光）来破坏饮用水源中的 PFAS。 VUV），该技术旨在实现几乎完全破坏 PFAS，而不在饮用水中产生二次废物流或有毒副产品。 VUV 光是最容易获得和最有效的水电离光子源之一，因为它利用丰富的水分子作为光子敏化剂。 ，可以很容易地由普通紫外线灯产生，并且易于控制和操作，与其他良性化学品一起调节该光源可以创建一个高反应性环境，以有效破坏 PFAS，将水性 PFAS 转化为。这项工作将涉及与潜在客户合作的化学动力学研究、先进化学分析和技术扩展。该奖项是 NSF 的法定使命，并通过使用基金会的智力优势和评估进行评估，被认为值得支持。更广泛的影响审查标准。
