Biodegradation of Sulfonamide Antibiotics by Microalgae: Mechanistic Insights into Substituent-Induced Effects

ACS ES&T Water, Год журнала: 2024, Номер 4(6), С. 2422 - 2432

Опубликована: Май 3, 2024

Microalgae are a sustainable environmentally friendly wastewater treatment technology that has attracted much attention for use in the purification of antibiotic-containing wastewater. However, research into mechanisms involved microalgal antibiotic degradation is still initial stages, especially concerning relationship between pollutant structure and removal rate. This study comprehensively analyzed biodegradation microalgae from molecular perspective, examining four sulfonamide antibiotics (SAs) with different substituents as representative pollutants. exhibited efficiencies 86.15, 74.24, 60.14, 46.60% sulfathiazole, sulfamethazine, sulfadiazine, sulfamethoxazole, respectively. It noteworthy cytochrome p450 (CYP450) played central catalyzing role their metabolism. Further analysis dynamics simulations density functional theory calculations revealed geometric differences electronic effect variations caused by significantly affected catalytic activity CYP450 well overall reactivity SAs, resulting rates. Overall, SAs high binding energy, low energy gap, electrophilicity indices were more readily catalyzed evidenced pathways. These results provide valuable insights at level how affect rate microalgae.

In this work, Prussian blue analogues (CuFe-PBA) derived copper-iron sulfides/N-doped porous carbon composite (CuFe-NC-SP-x) was prepared as an effective peroxymonosulfate (PMS) activator to degrade sulfadiazine (SDZ). A strategy that kills two birds with one stone proposed construct CuFe-NC-SP-x, i.e., S-etched CuFe-PBA (CuFe-PBA-S) annealed NaH2PO2 in N2 atmosphere simultaneously introduce sulfur vacancy (Sv) and phosphorus doping. 40 μM SDZ completely removed by CuFe-NC-SP-2/PMS 20 min (0.2 g/L catalyst 0.5 mM PMS). The kobs value obtained CuFe-NC-SP-2 (0.48 min−1) nearly 33 17 times higher than of (0.014 CuFe-PBA-S (0.028 min−1), respectively. Quenching tests, electron paramagnetic resonance (EPR) analysis indicated PMS activation the system involved radical pathway (26.1 % OH 22.7 SO4–) non-radical (17.8 1O2 33.4 transfer process). OH, SO4– were mainly produced S enhanced metal sites for activation. synergistic effect Sv P doping enabled powerful mechanism. Electrochemical tests DFT calculations demonstrated existing CuFe-NC-SP-x improved donor ability increased adsorption energy toward PMS, accelerated transport from PMS. This work not only provides a novel synthesize high introducing phosphorous doing step, but also manages comprehensively understand mechanisms facilitated
