In this project funded by the Environmental Chemical Science Program in the Chemistry Division at the National Science Foundation, Professor Ching-Hua Huang of the Georgia Institute of Technology in Atlanta seeks to better understand peroxy acids (POAs) as emerging disinfectants and oxidants to replace chlorine in wastewater treatment facilities. Despite the growing interest and pilot- to full-scale implementation of POAs in wastewater treatment, the understanding POAs trails behind their applications. The objective of this project is to provide a comprehensive understanding of the chemistry of POAs in water. This project has multiple broader impacts. It establishes an active collaboration with industry partners in evaluating on-going field tests of POA-based processes. The research enhances graduate and undergraduate student education by promoting the participation of underrepresented groups. The new knowledge and improved POAs-based technology benefits society by providing in safe water treatment technology, clean water and sanitation, and smart water management. All of the applications protect human health and the ecosystem.The intellectual contribution of this study is to provide new fundamental knowledge on the chemistry of POAs and their radical-based advanced oxidation processes. Such processes may effectively destroy water pollutants. Specific research aims include: investigating the chemical oxidation of organic micropollutants, biomolecules and structurally representative compounds by POAs; characterizing the ultraviolet (UV)/POA process; investigating the degradation of organic micropollutants and biomolecules under UV/POA; assessing the water matrix effect on the POA and UV/POA processes; developing kinetic modeling for the POA and UV/POA processes; and performing quantum chemical evaluation of oxidation reactions by POAs and UV/POA. The new knowledge improves the POA and UV/POA technologies.

在这个由国家科学基金会化学部环境化学科学计划资助的项目中，亚特兰大格鲁吉亚理工学院的黄清华教授试图更好地了解过氧酸（POAs）作为新兴的消毒剂和氧化剂，以取代废水处理设施中的氯。尽管人们对POAs在废水处理中的应用越来越感兴趣，并从试点到全面实施，但对POAs的理解落后于其应用。该项目的目标是提供对水中POAs化学的全面了解。该项目具有多个更广泛的影响。它与行业合作伙伴建立了积极的合作关系，以评估基于POA工艺的持续现场测试。这项研究通过促进代表性不足的群体的参与来加强研究生和本科生的教育。新的知识和改进的POAs技术通过提供安全的水处理技术、清洁的水和卫生设施以及智能水管理来造福社会。 所有的应用都保护人类健康和生态系统。本研究的智力贡献是提供有关POAs化学及其基于自由基的高级氧化过程的新的基础知识。 这些过程可以有效地破坏水污染物。具体的研究目标包括：研究POA对有机微污染物、生物分子和结构上有代表性的化合物的化学氧化;表征紫外（UV）/POA过程;研究在UV/POA下有机微污染物和生物分子的降解;评估水基质对POA和UV/POA过程的影响;开发POA和UV/POA过程的动力学模型;以及通过POA和UV/POA进行氧化反应的量子化学评价。新知识改进了POA和UV/POA技术。
