Using biomass-based catalysts in biodiesel production can make the process more economical and environmentally friendly. In this study, a new magnetic nanocatalyst was developed using banana peel biochar, ZIF-67, Fe3O4, K2CO3, then utilized catalytic transesterification to convert waste cooking oils (WCO) into biodiesel. The level of free fatty acids treated WCO (WCOT) reduced generate with suitable characteristics. physicochemical aspects were characterized by Fourier-transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) map techniques. process, effect temperature, methanol-to-oil ratio, time, weight on potential produce from WCOT explored. highest yield (96.82%) (99.18%) attained at 65 °C, 3 wt %, ratio 19:1, processing time h, mixing rate 600 rpm. Based thermodynamic studies, endothermic non-spontaneous. regeneration studied various solvents n-hexane had good ability recover catalyst (90% up 5 stages). results 1H NMR test revealed that desired high WCOT. properties produced met ASTM D6751 EN 14214 standards.

Pharmaceutical industry wastewater is causing an increased risk of resistant pharmaceutical micropollutants (PMP) e.g. antibiotic bacteria (super bug) in the ecosystem. Amongst variety treatment approaches, Advanced oxidation processes (AOPs) employing photocatalysis provides a cost-effective and sustainable approach for fixation PMP economical efficient manner to counter potential risks. Until today, tremendous efforts have been made trig performance photocatalytic treatment, with key focus on development cost-effective, moderately stable photocatalyst. Such attempts succeeded different types photocatalysts using synthesis techniques. In recent years, graphitic carbon nitride (GCN) has emerged as one cost effective, stable, nontoxic photocatalyst, scarcely studied specifically (PMPs) degradation. Hence, considering these factors alongside facile moderate optical absorption GCN, effort was present work effective customization GCN i.e. silver (Ag) doping extend light visible range which may enhance Ciprofloxacin (CIP) The optimization executed varied Ag dopant content obtain optimum sample supreme activity maximum degradation CIP, common antibiotic. best Ag-doped (0.1 AGCN) exhibits efficiency 84%, 2.15 times greater than pure (39%). obtained results showed that strategy substantially enhances performance, thus offering mean developing active photocatalyst removal encouraging further research. prepared samples evaluated by CIP under irradiation. Several characterization techniques were used characterize analyze samples, such X-ray diffraction (XRD), Scanning electron microscopy (SEM), Raman spectroscopy, Fourier Transform Infrared (FTIR) UV Visible absorption, Photoluminescence (PL) spectroscopy.

Abstract Oxytetracycline (OTC) and ciprofloxacin (CIP) contamination have caused serious risks to human health, modified biochar is considered as a potential adsorbent for their removal. The typical agricultural waste of cotton husk was used the feedstock, then combined with γ-Fe 2 O 3 ball milling innovatively synthesize nano zero-valent iron (nZVI) supporting magnetic hush-derived (Fe @BMBC) by reductive calcination. Fe @BMBC performed excellent adsorption performance maximum capacity OTC (266.7 mg · g −1 ) CIP (83.36 ), its 1.6 2.3 times that (BC). Characterization analysis showed contained abundant oxygenated functional groups (e.g., -OH, C = Fe–O) surface covered diverse oxides. high magnetization sensitivity guaranteed it easily be separated magnet. Oxygenated participated in process, solution pH significantly affected behaviour, pseudo-second-order model Freundlich better fitting kinetics isotherms data. These results confirmed π-π conjugation, H-bonding, Fe–O complexation electrostatic interactions contributed greater @BMBC. Ethanol + ultrasound could efficiently regenerate maintain sustainable CIP. Additionally, good environmental security wide range (from 11) view low leaching risk Fe. Graphical
