The ubiquity of diclofenac (DCF) in the environment has raised significant concerns. Diclofenac is a non-steroidal anti-inflammatory drug that been found various environmental matrices at minimum concentrations are harmful to aquatic and terrestrial organisms. Traditional wastewater treatment plants (WWTPs) not fully equipped remove range pharmaceuticals, explains continued DCF surface waters. In this study, an Fe3O4/SiO2 nanocomposite prepared from acid mine drainage coal fly ash was applied for removal wastewater. Major functional groups (Si–O–Si Fe–O) were discovered FTIR. TEM revealed uniform SiO2 nanoparticle rod-like structures with embedded dark spherical nanoparticles. SEM-EDS analysis sponge-like structure fused Fe3O4 nanoparticles had Si, O, Fe content. XRD demonstrated crystalline nature nanocomposite. properties evaluated using BET 67.8 m2/g, 0.39 cm3/g, 23.2 nm area, pore volume, size, respectively. Parameters suspected be affecting process evaluated, including pH, dosage, sample volume. detection conducted on high-performance liquid chromatography diode-array (HPLC-DAD). Under optimum conditions, adsorption monolayer, physisorption described Langmuir Dubinin-Radushkevich (D-R) isotherm models. kinetic data best fitted pseudo-first order model, indicating process. thermodynamic experimental confirmed spontaneous. results obtained real water samples showed 95.28% 97.44% efficiencies influent effluent: 94.83% 88.61% raw sewage final sewage, Overall, work could successfully used
