Comparative Kinetic Analysis of Triclosan Degradation under UV-C and Simulated Solar Irradiation González Fernández, Lázaro Adrián Chems, Myriam Medellín Castillo, Nahum Andrés Castillo Ramos, Ventura Sánchez Polo, Manuel Vilasó Cadre, Javier E. Ocampo-Pérez, Raúl Triclosan degradation UV-C irradiation Simulated solar irradiation This research delves deeply into the intricate degradation kinetics of triclosan, employing two distinct methodologies: UV and simulated solar irradiation. Through a comprehensive comparative analysis, the study endeavors to elucidate the efficacy of these techniques, aiming to shed light on their respective methodological strengths and limitations. The study compares the efficacy of UV and simulated solar irradiation techniques for triclosan degradation, revealing that both methods exhibit effectiveness in degrading triclosan, with variations observed in degradation rates and byproduct formation. Through a detailed examination of the kinetics of triclosan degradation, the study reveals the intricate pathways and mechanisms involved in the photodegradation process. Results highlight the influence of irradiance levels and residence times on degradation efficiency. The research identifies optimal conditions for triclosan degradation, emphasizing the importance of residence time and irradiance levels. Results show that a residence time of 4 h and an irradiance level of 450W m−2 maximize degradation efficiency. Analysis of degradation byproducts provides insights into the transformation pathways of triclosan under UV and simulated solar irradiation, indicating the formation of 2,4-dichlorophenol, quinone, and hydroquinone as primary byproducts. 2024-09-19T10:42:13Z 2024-09-19T10:42:13Z 2024-04-25 journal article González-Fernández, L.A.; Chems, M.; Medellín-Castillo, N.A.; Castillo-Ramos, V.; Sánchez-Polo, M.; Vilasó-Cadre, J.E.; Ocampo-Pérez, R.
