The zero-valent iron (ZVI) has attracted increasing attention due to the enhanced reactivity of ZVI uranium wastewater. However, practical application is hampered its susceptibility oxidation and formation passivation layers during storage in situ restoration. To address these issues, we used a biosulfuration approach modify for ore wastewater treatment. A series physicochemical characterization tools photoelectronic analyses showed that BS-ZVI considerably increased carrier separation efficiency visible light absorption capacity, resulting significant photoassisted enhancement effect on extraction. Accordingly, removal reached 91% within 60 min, maximum adsorption capacity was 336.3 mg/g. By analyzing mechanism, improved U(VI) performance mostly responsible dissolution layer surface ZVI, generation Fe(II) FeS, important role Shewanella putrefaciens extracellular polymers (EPS). Overall, biohybrid merges with high activity bio-FeS, self-regeneration ability bacteria, expanding promising new sustainable treatment mine

Deciphering the Roles of Extracellular Polymeric Substances (EPS) in Shaping Disinfection Kinetics through Permanent Removal via Genetic Disruption

Environmental Science & Technology, Год журнала: 2024, Номер 58(15), С. 6552 - 6563

Опубликована: Апрель 4, 2024

Extracellular polymeric substances (EPS) ubiquitously encapsulate microbes and play crucial roles in various environmental processes. However, understanding their complex interactions with dynamic bacterial behaviors, especially during the disinfection process, remains very limited. In this work, we investigated impact of EPS on kinetics by developing a permanent removal strategy. We genetically disrupted synthesis exopolysaccharides, structural components EPS,
