Remediation of Surfactants Used by VUV/O₃ Techniques: Degradation Efficiency, Pathway and Toxicological Analysis.

ABSTRACT: Surfactants are increasingly used in systems that come into contact with the human body, such as food, pharmaceuticals, cosmetics and personal hygiene products. Increasing attention is being devoted to the toxic effects of surfactants in various human contact formulations, as well as the removal of residual surfactants. In the presence of ozone (O₃), anion surfactants-a characteristic micro-pollutant-such as sodium dodecylbenzene sulfonate (SDBS) in greywater, can be removed using radical advanced oxidation. Herein, we report a systematic study of the SDBS degradation effect of O₃ activated by vacuum ultraviolet (VUV) irradiation and the influence of water composition on VUV/O₃, and determined the contribution of radical species. We show a synergistic effec
