Abstract

Perfluoroalkylated and polyfluoroalkylated substances (PFAS) are a large family of synthetic chemicals widely used to manufacture various commercial products. However, they are hazardous to health and the environment. These substances are very persistent and their degradation requires advanced degradation techniques. One of the most widely used technologies for this purpose is advanced oxidation processes (AOP). This study aims to evaluate the use of AOP in PFAS degradation based on their efficiency, parameters influencing each process, advantages, disadvantages, and associated research challenges. According to the results, plasma, electrochemical oxidation, sonochemical oxidation, and heterogeneous photocatalysis stand out among the AOP applied for PFAS degradation. In addition, perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) were found to be the main toxic compounds studied. In this regard, future research should focus on a wider variety of PFAS. Finally, the drawbacks associated with the application of these processes to eliminate the substances of interest were found to be an urgent need to be overcome.

高级氧化法处理水中全氟烷基化物质

全氟烷基化和多氟烷基化物质(PFAS)是一类广泛用于制造各种商业产品的合成化学品。然而，它们对健康和环境是有害的。这些物质非常持久，它们的降解需要先进的降解技术。为此目的使用最广泛的技术之一是高级氧化过程(AOP)。本研究旨在评估AOP在PFAS降解中的使用，基于它们的效率、影响每个过程的参数、优点、缺点和相关的研究挑战。结果表明，等离子体、电化学氧化、声化学氧化和多相光催化是降解PFAS的主要方法。此外，研究发现全氟辛烷磺酸(PFOS)和全氟辛酸(PFOA)是主要的有毒化合物。在这方面，未来的研究应侧重于更广泛的PFAS。最后，发现与应用这些方法消除感兴趣的物质有关的缺点是迫切需要克服的。
