Use of Fenton‐Oxidation and a Helicoidal Flux Reactor in the Removal of Doxycycline: Optimization and By‐Products Identification

Chemical Engineering & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 30, 2025

Abstract Doxycycline (DOX) is a contaminant present in different water bodies. Fenton and photo‐Fenton are two advanced oxidation technologies with high potential for environmental remediation. This study aimed to eliminate DOX from aqueous solutions using Fenton, photo‐Fenton, helicoidal flow reactor. The experimental conditions related the presence of ferrous ions hydrogen peroxide were optimized. After 60 min reaction, extents pollutant elimination mineralization ∼85.0 % ∼30.0 %, respectively. Hydroxyl radicals identified as agents responsible under evaluated conditions. Finally, some reaction by‐products identified, removal route was proposed.

Comparison of UV/PAA and VUV/PAA Processes for Eliminating Diethyl Phthalate in Water

Water, Год журнала: 2024, Номер 16(23), С. 3533 - 3533

Опубликована: Дек. 8, 2024

Diethyl phthalate (DEP) is a commonly utilized plasticizer that has gained significant attention due to its widespread occurrence in the environment and harmful impact on human health. The primary objective of this study was evaluate compare several (ultraviolet) UV-(peracetic acid) PAA advanced oxidation processes based hydroxyl radicals degrade DEP. effect UV-LEDs incorporating at different UV ranges (UV-A, λ = 365 nm; UV-C, 254 nm VUV, nm) evaluated. results demonstrated DEP successfully degraded both UVC/PAA (removal rate 98.28%) VUV/PAA 97.72%) compared UVA/PAA process 2.71%). competitive method evaluated contribution R-O•, which were 24.08% 33.92% processes, respectively. We also effects peroxymonosulfate (PMS) dosages, irradiation, pH anion coexistence removal In system, degradation particularly effective about 95.52%) over wider range (3–9). As concentration HCO3− ions increased, there may have been some inhibition removal. inhibitory HA Cl− negligible. Analysis intermediates revealed primarily occurred via two pathways: hydrolysis hydroxylation reactions. This presents potential mnethod for phthalates offers guidance selection appropriate disinfection technologies drinking water treatment.
