Abstract

Per- and polyfluoroalkyl substances (PFAS), man-made ‘forever chemicals’, have been extensively released into the environment. Currently, adsorption is the chief option for removing PFAS from contaminated water. However, the regeneration and reactivation of PFAS-laden adsorbents are still a challenging task, and several investigations are ongoing to find the most suitable technology. The current state of research and development on available techniques for PFAS-laden adsorbents, mainly granular activated carbons (GACs), is provided in this article with a particular focus on thermal-based processes. Despite the growing research on PFAS degradation pathways, future investigations are needed to systematically assess the interplay between PFAS and co-adsorbed organic and inorganic species and to pursue on-site regeneration avoiding further transportation and/or disposal of exhausted materials.

负载全氟烷基和多氟烷基物质的颗粒活性炭再生和再活化技术研究现状

全氟烷基和多氟烷基物质(PFAS)是人造的“永久化学品”，已广泛释放到环境中。目前，吸附是去除污染水中PFAS的主要选择。然而，装载pfas的吸附剂的再生和再激活仍然是一项具有挑战性的任务，并且正在进行一些研究以找到最合适的技术。本文介绍了含pfas吸附剂(主要是颗粒活性炭)的现有技术的研究和发展现状，并重点介绍了基于热的工艺。尽管对PFAS降解途径的研究越来越多，但未来的研究需要系统地评估PFAS与共吸附的有机和无机物种之间的相互作用，并寻求现场再生，避免进一步运输和/或处理耗尽的物质。

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
