I-Corps: Coupled High and Low-Frequency Ultrasonic for the Destruction of Organics

这个I-Corps项目的更广泛的影响/商业潜力是促进用于破坏危险化学品的功率超声的发展。该技术可以潜在地用于工业和实验室有机废物处理，污染土壤/沉积物的修复/处理以及水和废水处理。该技术为降解有毒有机污染物提供了一种经济有效的方法，消除了昂贵的活性炭或其他吸附剂的使用，并在源头产生了有机污染物的原位去除。这个I-Corps项目探索与功率超声相关的声化学的翻译，以开发一种新的环境修复技术，用于降解PFAS， PCB， PAH等污染物。商业上可用的补救方法使用吸附和稳定技术或焚烧，但这些对某些类别的污染物无效，焚烧是一种昂贵的替代方法。该项目探索不需要额外化学品的声化学反应和声物理热解；该项目将描述未来的参数优化，包括频率、换能器选择和反应堆几何形状。该奖项反映了美国国家科学基金会的法定使命，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。

The broader impact/commercial potential of this I-Corps project is to advance the development of power ultrasound for the destruction of hazardous chemicals. This technology can potentially be used for industrial and laboratory organic waste treatment, remediation/treatment of polluted soils/sediments, and water and wastewater treatment. The technology offers a cost-effective method for degrading toxic organic pollutants, eliminating the use of costly activated carbon or other adsorbents, and generating in situ removal of organic contaminants at the source. This I-Corps project explores translation of the sonochemistry associated with power ultrasound to develop a new environmental remediation technology for the degradation of pollutants such as PFAS, PCB, PAH, etc. Commercially available remedial approaches use sorption and stabilization techniques or incineration, but these are ineffective for certain classes of pollutants and incineration is an expensive alternative. This project explores sono-chemical reactions and sono-physical pyrolysis without requiring additional chemicals; the project will characterize the future optimization of parameters including frequency, transducer selection, and reactor geometry.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.
