“…At the same time, excessive use of H2O2 is not recommended as residual H2O2 concentration contributes to COD. In a similar study, 100 mg/L was found to be the optimum value for H2O2 concentration by looking at the efficiency of tetracycline and COD removal (Gürtekin et al, 2022). In the oxidation of carbofuran by Fenton process, 81% of carbofuran was degraded at a concentration of 100 mg/L H2O2 (Ma et al, 2010).…”

In this study, degradation of oxytetracycline (OTC) and chlortetracycline (CTC) was investigated by Fenton process. In experimental studies conducted for this purpose, different values of pH, Fe2+ concentration, H2O2 concentration and reaction time were tested as important parameters for the Fenton process and optimum conditions for OTC and CTC removal were determined. For both antibiotics, the optimum values of the parameters in the Fenton process were the same, and these values were found to be 3 for pH, 20 mg/L for Fe2+ concentration, 25 mg/L for H2O2 concentration, 5 min for reaction time. Under these optimum conditions, OTC degradation was 100%, CTC degradation was 99.68%, chemical oxygen demand (COD) removal efficiency for oxytetracycline (O-COD) was 89.6%, COD removal efficiency for chlortetracycline (C-COD) was 88.5%. These results show that the Fenton process is an effective method that can be used for OTC and CTC degradation.

“…In fact, a degradation of 38.2% was obtained at 10 kHz, which is similar to the value observed with flow-mode HC alone (36.4%), while it was 51.7% with 48 kHz, confirming that 48 kHz was the best frequency to be applied for HC/ED treatment. A typical Fenton process on a total volume of 250 mL has previously been performed by Gurtekin et al, 37 on a 100 mg/L solution of TC in a 250 mL flask under magnetic stirring. The authors observed the complete degradation of the antibiotic after 10 min of reaction (performed at pH 4), and 15 additional minutes of sedimentation, using two solutions of Fe 2+ and H 2 O 2 at concentrations of 30 mg/L and 100 mg/L, respectively.…”

Tetracyclines are widely used antibiotics that are often carelessly released into the environment, posing a potential threat to the ecosystem. Due to the lack of efficient methods to remove tetracyclines from wastewater, a remarkable research effort on the remediation of tetracyclines has been undertaken. The synergistic effect of hydrodynamic cavitation (HC) and electrical discharge (ED) plasma on the degradation of a number of antibiotics in water has been studied in this work. Catalyst- and oxidant-free processes have been carried out using a new pilot-scale hybrid device (HC/ED plasma) working in flow-through mode (330 L/h). Tetracycline hydrochloride (TC), doxycycline hyclate (DC) and oxytetracycline dihydrate (OC) were selected as the model compounds. Antibiotic degradation tests were performed using a 5 L water solution at various antibiotic concentrations (10, 25, 50, 75, and 100 mg/L). All experiments were performed over 15 min, and samples were either collected using the flow-through method, or every 5 min when using the loop configuration. The temperature was kept constant at 30 °C, with fluctuations of ±2 °C. The influence of applied HC input pressure (45, 60, and 70 bar), applied ED amplitude frequency (10 and 48 kHz) and the pH values of the initial solutions (2 and 11) on antibiotic degradation rate have been investigated. Near quantitative TC (>98%), DC (98%) and OC (95%) degradation was documented after only 15 min of combined HC/ED plasma treatment at 70 bar and 48 kHz. To better understand the synergistic effect of coupled HC/ED treatment on antibiotic degradation, a dosimetry assay was performed to quantify the oxidizing compounds generated by this technology. Specifically, the coupled HC/ED plasma treatment was able to linearly increase the amount of oxidants in water as a function of time, reaching a maximum concentration of 13.426 mmol/L after 15 min, which is more than 85-times higher than that of HC alone (0.153 mmol/L). This study demonstrates the impressive efficiency of hybrid HC/ED plasma technology in degrading recalcitrant antibiotics in wastewater without the need for catalysts and oxidants.

Nanomaterials have a wide range of applications including novel biomedical studies are devoted to improving the functionality and effectively of traditional and unmodified systems, both drug carriers and common scaffolds for tissue engineering or advanced hydrogels for wound healing purposes. In this regard, metal oxide nanoparticles show great potential as versatile tools in biomedical science. In particular, iron oxide nanoparticles with different shape and sizes hold outstanding physiochemical characteristics, such as high specific area and structure that make them unique nanomaterials to be used in diverse aspects of medicine and biological systems. The challenges associated with the uncontrolled presence of antibiotics such as tetracycline in the environment have necessitated their removal through different techniques. Tetracycline is hard to degrade in living organisms and can even be converted to more toxic substances. In this article different type of iron oxides were subjected to photo degradation of antibacterial drug Tetracycline under UV light illumination and direct sunlight and the results were promising to degrade the drug within 20 min. The SEM, TEM, EDAX and XRD for the catalyst were characterized to confirm the presence of iron oxide, the size and shape of the particle. The kinetics of photo degradation of tetracycline followed the pseudo-first-order mechanism, proceeding through hydroxyl radicals generated under illumination. Moreover, the photo generated hydrogen peroxide could lead to heterogeneous photocatalytic processes on the surface of iron oxide nanoparticles; additionally generating hydroxyl and hydroperoxyl radicals enables photo degradation of tetracycline.
