In this research, Fe3O4@HZSM-5 magnetic nanocomposite was synthesized via a coprecipitation method for metronidazole (MNZ) degradation from aqueous solutions under ultrasonic irradiation which showed superb sonocatalytic activity. The magnetite characterized by using field-emission scanning electron microscope-energy dispersive X-ray Spectroscopy, (FESEM-EDS), Line Scan, Dot Mapping, diffraction (XRD), vibrating sample magnetometer (VSM), and Brunauer-Emmett-Teller (BET). To investigate the activity of nanocomposite, removal conditions were optimized evaluating influences operating parameters like dosage catalyst, reaction time, pH, concentration H2O2, MNZ concentration, pH on removal. maximum efficiency TOC at time 40 min, catalyst dose 0.4 g/L, H2O2 1 mM, initial 25 mg/L, 7 achieved 98% 81%, respectively. Additionally, in real wastewater optimal obtained 83%. results that Langmuir-Hinshelwood kinetic model KL-H = 0.40 L mg-1, KC 1.38 mg/L min) can describe process. radical scavenger tests indicated major reactive oxygen species formed hydroxyl radicals Sono-Fenton-like Evaluation reusability an 85% reduction after seven cycles. Based results, it be concluded as heterogeneous nano-catalysts to effectively degrade MNZ, observed stability recyclability demonstrated promising treatment contaminated with antibiotics.

Phthalate esters (PAEs) are normally used as plasticizers and has potential to leach out from various polymeric materials. Their presence in different environmental matrices become a significant concern, they endocrine disrupting compounds causing reproductive, genetical, developmental abnormalities. As result, it is urgent develop robust technology that can mineralize these contaminants the environment. This review focuses on origin fate of PAEs environment, their exposure routes health effects, remediation strategies wastewater. The article largely in-depth understanding physicochemical, biological advanced oxidation processes currently being for treatment PAEs. In addition, based physicochemical properties molecules, adsorption interaction mechanisms with adsorbents introduced. also explores range materials be an adsorbent photocatalyst composite enhance performance by followed mineralization. For large scale removal, semiconductor photocatalysis integrated seems effective technique removal mineralization Finally, scaling up photocatalytic technology, parameters such as, improved reactor design, role water matrix economic aspects were discussed future research directions catalyst agglomeration, modification, synthesis proposed. Therefore, techno-economic perspectives factors like, improving active sites rate, self-cleaning surface, renewable light sources, radical scavenging organic matter recovery need addressed transforming process form 'lab' 'land'.

In this study, 0.6Ag3PO4/CoWO4 composites were synthesized by hydrothermal method. The prepared materials systematically characterized techniques of scanning electron microscope (SEM), transmission (TEM), X-ray diffractometer (XRD), photoelectron spectroscopy (XPS), N2 adsorption/desorption, and UV–vis diffuse reflectance spectrum (DRS). Furthermore, the sonocatalytic degradation performance towards tetracycline (TC) was investigated under ultrasonic radiation. results showed that, combined with potassium persulfate (K2S2O8), achieved a high efficiency 97.89 % within 10 min, which much better than bare Ag3PO4 or CoWO4. By measuring electrochemical properties, it proposed that mechanism is formation S-scheme heterojunction, increases separation electron-hole pairs (e--h+) generates more electrons holes, thereby enhancing activity. scavenger experiments confirmed hole (h+) primary active substance in degrading TC, free radicals (OH) superoxide anion radical (O2–) auxiliary substances. indicated nanocomposites could be used as an efficient reliable sonocatalyst for wastewater treatment.
