The active free radical species vary with supporting electrolyte during electrochemical advanced oxidation processes, thus, resulting into the significant difference in removal rate and degradation pathways of organic compounds. Herein, behavior tetracycline (TC) is studied based on boron‐doped diamond anode Na 2 SO 4 , NaCl, NaNO 3 systems. It revealed that ClO − initialize reaction TC followed by gradual through • OH. Notably, enhanced lifetime compared to ensures a more effective prolonged TC. Thus, NaCl system remarkably larger than Despite different across each system, consistent mechanism identified: initial hydroxylation occurs at arbitrary positions further hydroxyl group form aldehyde or ketone. Ketones undergo direct facilitate ring‐opening reaction; whereas aldehydes are oxidized carboxylic acid eventually transform H O CO . This work sheds deep insights compounds various electrolytes, which benefits efficient practical applications.

Accelerated Pollutant Degradation by UV/H₂O₂ at the Air–Water Interface of Microdroplets

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

Ultraviolet light-induced homolysis of hydrogen peroxide (UV/H2O2) can generate powerful hydroxyl radicals (•OH) for sustainable water purification. However, the efficiency conventional bulk-phase UV/H2O2 system is limited by low yield and utilization •OH, in turn necessitating high UV energy input long purification period. In this study, we present an innovative microdroplet enhanced pollutant degradation. The degradation pollutants sprayed microdroplets was accelerated 8.5-63.3-fold compared to those bulk water, demonstrating universal effectiveness across a range types diverse aqueous matrices. This enhancement stems from elevated •OH production at air-water interface due absorbance H2O2. 45-fold higher than that facilitating rapid •OH-mediated Moreover, accumulate interface, where concentrated, leading mediating before quenching. Our findings provide solution overcome bottlenecks utilization, offering insights improving treatment systems.
