In the present study, magnetic NH2-MIL-101(Al)/chitosan nanocomposite (MIL/Cs@Fe3O4 NCs) was synthesized and used in removal of azithromycin (AZT) from an aqueous solution for first time. The as-synthesized MIL/Cs@Fe3O4 NCs characterized by SEM, TEM, XRD, FTIR, BET, VSM techniques. effect various key factors AZT adsorption process modeled optimized using response surface methodology based on central composite design (RSM-CCD). low value p-value (1.3101e-06) RSD (1.873) parameters, along with coefficient determination > 0.997 implied that developed model well fitted experimental data. Under conditions, including pH: 7.992, adsorbent dose: 0.279 g/L, time: 64.256 min concentration: 10.107 mg/L, efficiency capacity were obtained as 98.362 ± 3.24% 238.553 mg/g, respectively. fitting data Langmuir isotherm (R2: 0.998, X2: 0.011) Pseudo-second-order kinetics 0.999, 0.013) showed is monolayer chemical nature. ΔH° 0, ΔS° ∆G° < 0 indicated spontaneous endothermic Magnesium more complicated than other background ions. Reuse 10 consecutive experiments reduced about 30.24%. performance under real conditions also tested promising results achieved, except treatment raw wastewater.

Two new highly-efficient and eco-friendly biosorbents comprised of magnetite, chitosan Chlorella vulgaris (MCC) or Arthrospira platensis (MCA) were prepared in such a way to be easily separated reused for removing different classes antibiotics as tetracycline (TC), ciprofloxacin (CIP) amoxicillin (AMX) from wastewater. They characterized using SEM, FTIR TGA. Biosorption experiments performed investigate the impact pH, biosorbent dosage, initial antibiotic concentration, contact time, concentration background electrolytes (NaCl, KCl CaCl2) on adsorption. Both biocomposites showed outstanding performance removal. Equilibrium data modelled Langmuir, Freundlich, Temkin, Dubinin-Radushkevich adsorption isotherms, among which first one gave best fit, with maximum TC, CIP AMX capacities 834.0, 394.9, 150.8 mg/g MCA 831.1, 374.2, 140.2 MCC, respectively. To follow time-evolution, pseudo-first-order, pseudo-second-order intraparticle diffusion kinetic models tested, second proved best-fitting one. Thermodynamic parameters revealed that was spontaneous endothermic. regenerated through microwave-assisted treatment repeatedly up four cycles, losing at equilibrium by no >7, 4 9 %, This study suggests both may effective sustainable alternatives commercial adsorbents

In the quest for eco-conscious innovations, this research was designed sustainable synthesis of magnetite (Fe3O4) nanoparticles, using ferric chloride hexahydrate salt as a precursor and extract Eucalyptus globulus leaves both reducing capping agent, which are innovatively applied photocatalyst photocatalytic degradation antibiotics "ciprofloxacin amoxicillin". Sugar cane bagasse biomass, sugar pyrolyzed biochar, magnetite/sugar biochar nanocomposite were also synthesized via environmentally friendly organized approaches. The optimum conditions ciprofloxacin amoxicillin found to be pH 6 5 amoxicillin, dosage (0.12 g), concentration (100 mg/L), irradiation time (240 min). maximum efficiencies percentage (73.51%) > (63.73%) (54.57%) (74.07%) (61.55%) (50.66%) magnetic nanocomposites, respectively. All catalysts demonstrated favorable performance; however, "magnetite/SCB biochar" exhibited most promising results among various employed in antibiotics. Kinetic studies performed, notably, pseudo-first-order chemical reaction showed best Through comprehensive comparative analysis three unique photocatalysts, identified optimal efficient treatment drug-contaminated wastewater, thus amplifying practical significance findings. recycling nanoparticles through separation, coupled with their functional modification integration into composite materials, holds significant application potential
