Abstract Ciprofloxacin (CIP) is the commonly prescribed fluoroquinolone antibiotic and one of top ten emerging pharmaceutical contaminants in world. It can pose a potential health risk if its residues enter body. In this study, adsorption CIP onto magnetic iron oxide nanoparticles coated with silver (Fe 3 O 4 @AgNPs) was evaluated. Fe @AgNPs were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X‐ray Diffraction (XRD), Scanning Electron Microscope (SEM). The parameters affecting on nanoadsorbent investigated including adsorbent dose, pH, contact time, salt content, mixing speed. highest efficiency removal achieved at pH 6, dose mg l −1 , content 1 % (W/V) shaking rate 100 rpm. process followed Freundlich isotherm model, kinetics pseudo‐second order maximum capacity 125 g .

Antibiotic contamination has become a severe issue and dangerous concern to the environment because of large release antibiotic effluent into terrestrial aquatic ecosystems. To try solve these issues, plethora research on withdrawal been carried out. Recently photocatalysis received tremendous attention due its ability remove antibiotics from aqueous solutions in cost-effective environmentally friendly manner with few drawbacks compared traditional photocatalysts. Considerable focused developing advanced visible light-driven photocatalysts order address problems. This review provides an overview recent developments field photocatalytic degradation antibiotics, including doping metals non-metals ultraviolet photocatalysts, formation new semiconductor advancement heterojunction building surface plasmon resonance-enhanced systems.

Antibiotics are widely used in medicine, but they not fully metabolized the body and can end up wastewater. Conventional wastewater treatment methods fail to completely remove antibiotic residues, which then enter rivers streams. Adsorption is a promising technique for removing antibiotics from wastewater, even at low concentrations. The successful one-pot synthesis of an adsorbent, iron-containing porphyrin-based porous organic polymer (Fe-POP), was achieved through reaction pyrrole groups terephthalaldehyde presence FeCl3. Characterized by substantial BET surface area 597 m2 g–1, Fe-POP systematically investigated its adsorption potential removal Ciprofloxacin (CIP) aqueous solutions. By systematic variation key parameters, including pH, adsorbent loading, CIP concentration, conditions were optimized. Under optimal pH = 3, concentration 5 ppm, 25 mg Fe-POP, maximum capacity reached impressive 263 g–1. robust behavior elucidated fitting experimental data Langmuir isotherm (R2 0.962) pseudo-second-order kinetic model 0.999) with lower error values. These models suggested that process predominantly involved chemical interactions between molecules surface. exhibited structure high capacity, showcasing efficacy contaminants water. Therefore, be considered valuable water applications, specifically removal.
