Removal of tetracycline by ultraviolet/sodium percarbonate (UV…
2024年4月15日 · In the UV process alone, TC removal reached 22.1 % within 15 min, indicating that UV had some influence on TC removal but with limited effectiveness. However, the removal efficiency significantly improved in both the UV/SPC and UV/H2 O 2, underscoring the strong synergistic effect of UV in conjunction with SPC and H 2 O 2.
Mechanisms of Cu(II) enhancing photolysis of tetracycline under UV ...
2023年10月15日 · In this study, we investigated the photolytic fate of TC induced by Cu (II) under UV irradiation. Cu (II) significantly promoted the removal of TC with photolysis rate constant of 0.467 h −1 at TC:Cu (II) molar ratio = 1, which was 49.04% higher than that without Cu (II) (0.238 h …
Visible-Light-Driven Photocatalytic Degradation of Tetracycline …
2022年9月9日 · With an enhanced surface area of nanotubes and a reduced band gap of 2.58 eV, 1.5 g/L concentration of 10% C-TAC showed the highest efficiency of visible-light-driven photodegradation (∼100% photodegradation rate in 60 min) of tetracycline at pH 5, 7, and 9. The photodegradation efficiency is not depleted up to five consecutive batch cycles.
Effect of UV - National Center for Biotechnology Information
2021年10月24日 · In this study, we compared the UV A and UV C photocatalytic processes for TC removal using MAC obtained from the almond green hull, coated with CuS. Additionally, the effects of different variables including pH, nanocomposite dosage, and pollutant concentration throughout different contact times were investigated.
Photocatalytic Degradation of Tetracycline by Z-Scheme Bi
2022年6月3日 · The results indicated that 10 mg of B/Z/5/1 offered the best photocatalytic activity under UV light, achieving 97.8% degradation of TC (20 mg/L) within 80 min. The measured rate constant (k) for TC degradation was almost 3 times that of pure Bi 2 WO 6.
Photocatalytic degradation of tetracycline antibiotic by a novel ...
2022年2月1日 · This work aims to elucidate the issues: (i) the photocatalytic performance of the Bi 2 Sn 2 O 7 /Bi 2 MoO 6 heterojunctions in elimination of TC; (ii) the influence of significant factors (e.g. catalyst dosage, pH, various foreign ions, organic molecule, and practical water bodies) on the photocatalytic performance; (iii) the ROS generation ...

Effect of UVC and UVA Photocatalytic Processes on ... - ResearchGate
2021年10月24日 · Due to deficient and weak adsorption of TC antibiotics by organisms in human and animal bodies, the defecated TC would penetrate domestic sewage either through uri-
(a) UV spectra of tetracycline (TC, 0.05 mM) in the presence and ...
Tetracyclines (TCs) have metal chelation properties and form strong complexes with iron ions under acidic conditions. In this study, we exploit this property as a strategy for low cost, rapid...
A review on tetracycline removal from aqueous systems by …
Tetracycline (TC), a frequently used drug for human and veterinary therapeutics, is among the most common antibiotic residues found in nature. Lack of advanced treatment techniques in the wastewater treatment plants (WWTPs) to remove residual TC from domestic and hospital wastewater poses a serious environmental risk.
