Synergistic degradation of metronidazole and penicillin G in aqueous solutions using AgZnFe2O4@chitosan nano-photocatalyst under UV/persulfate activation

Environmental Technology & Innovation, Год журнала: 2024, Номер 35, С. 103724 - 103724

In recent years, the persistence of pharmaceutical contaminants like metronidazole (MNZ) and penicillin G (PG) in water bodies has become a major environmental concern. The present research studied simultaneous degradation MNZ PG utilizing an AgZnFe2O4@Ch catalyst generated through co-precipitation technique as effective stimulator for persulfate (PS) existence UV light. structure was characterized using X-ray powder diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy, vibrating-sample magnetometer, energy dispersive spectroscopy mapping. After 50 minutes reaction time under ideal operating conditions, which included 0.4 g/L catalyst, 4 mM PS, 5 mg/L PG, pH 5, highest 81.5 % 82.3 were obtained. Statistical parameters, including R2 values 0.985 0.981 indicate very good agreement between predicted observed values. Garson's method analysis revealed that PS dosage had greatest impact on degradation, while initial concentration exerted most significant influence degradation. Langmuir-Hinshelwood model surface rate constants (Kc) 0.954 (mg/L.min) adsorption equilibrium (KL-H) 0.032 (L/mg) both antibiotics, respectively. claimed mechanism illustrated by free radical scavenging studies, demonstrated SO•4- radicals main involved PG. A last investigation catalyst's regeneration it satisfactory chemical stability after five cycles usage approaches.

Green construction of magnetic MnFe2O4/ZIF-8 nanocomposite utilizing extract of Melissa officinalis plant for the photo-degradation of tetracycline under UV illumination

Catalysis Communications, Год журнала: 2023, Номер 185, С. 106798 - 106798

Опубликована: Ноя. 5, 2023

The current work explores the photocatalytic degradation of tetracycline utilizing ZIF-8 grafted with MnFe2O4 through a facile green approach. complete was achieved at optimized circumstances (pH = 9, catalyst concentration 0.5 g/L, contact time 180 min, and 20 mg/L dose). decontamination reaction as-made more adherence to pseudo-first-order model. Recycling experiments demonstrated excellent stability MnFe2O4/ZIF-8 composite after six regeneration runs. Furthermore, as-constructed can simultaneously eliminate tetracycline, COD, TOC from real wastewater by 84%, 65%, 50%, respectively, revealing its robust potential in addressing water contamination concerns.
