The contamination of water sources by pharmaceutical pollutants presents significant environmental and health hazards, making the development effective photocatalytic materials crucial for their removal. This research focuses on synthesis a novel Ag/CuS/Fe₃O₄ nanocomposite its efficiency against tetracycline (TC) diclofenac contaminants. was created through straightforward scalable precipitation method, integrating silver nanoparticles (AgNPs) copper sulfide (CuS) into magnetite framework. Various analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR),ultraviolet–visible spectrophotometry (UV–Vis) energy-dispersive (EDS), were employed to characterize structural morphological properties synthesized material. activity tested degrading under visible light. Results indicated marked improvement in performance (98%photodegradation TC 60 ppm 30 min) compared both pure CuS/Fe₃O₄. enhanced is attributed synergistic interaction between AgNPs, CuS, Fe3O4, which improves light absorption charge separation, thereby increasing generation reactive oxygen species (ROS) promoting degradation pollutants. rate constant k photodegradation about 0.1 min−1 catalyst dosages 0.02 g. Also effect photocatalyst dose concentration pH solution tested. modified also used simultaneous successfully. study highlights potential as an efficient reusable eliminating from water.

Abstract Due to waste, pollution, and unequal distribution of the world’s finite freshwater resources, there is currently a problem water scarcity. Therefore, developing novel, affordable, efficient techniques for purification essential. Here, photo-assisted degradation Methyl Orange dye (MO) under visible light UV was achieved by using reduced graphene oxide (RGO) photocatalyst loaded with Zn 0.5 Cu Fe 2 O 4 (ZCF) called MRGO 20. Furthermore, all prepared samples were characterized X-ray diffraction (XRD), fourier transformation infrared (FTIR), transmission electron microscope (TEM), vibrating sample magnetometer (VSM) Raman analysis. After 40 minutes, high photocatalytic efficacy effectively eliminated about 96 % 10 ppm MO 20 mg NPs at pH 5 Visible irradiation. From results, demonstrated good performance stability after five cycles dye. The shown generated in both may motivate further investigation into more potent photocatalysts filtering. nanocomposite displayed great activity against Gram-negative ( E. coli ) bacteria zone inhibition (ZOI) mm value 24.0 mm, biofilm 94.3%. produced samples’ observed encourage continued research effective filtration biological applications.
