Abstract

Artificial sweeteners (ASs) are widely detected in aquatic environments due to their high solubility and long half-lives. The growing concern regarding their environmental persistence and potential risks to human health highlights the need for effective treatment technologies. Advanced oxidation processes (AOPs) have emerged as promising methods for ASs removal, offering energy efficiency and the potential for complete mineralization. It emphasized the effectiveness, degradation pathways and influencing factors associated with photocatalytic oxidation, electrocatalytic oxidation and ozonation, as well as their synergistic application with Fenton and persulfate oxidation. The integration of light and electrical energy significantly enhanced the activation of oxidants, leading to efficient and rapid degradation. Ozone showed substantial potential due to its ability to generate a high amount of hydroxyl radicals upon activation. This review summarizes common ASs and their removal by AOPs. Considering removal efficiencies, it is suggested that ASs with a bicyclic structure is more suitable for synergistic AOPs removal. Challenges include the stability of bicyclic structures and prolonged treatment time. Future research should focus on optimizing reaction systems and scaling up these processes for practical applications.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
