Abstract Synthetic dyes are predominantly emitted into the eco-environment resulting, in harmful effects on environment and human. This study presents a new perspective mesoporous silica (SBA-16) reduced graphene oxide (rGO) obtained from rice husk ash as substrates for Fe 3 O 4 nanoparticles (NPs) to investigate their morphological Fenton catalytic characteristics towards degradation of synthetic acid blue 40 dye (AB40). The adsorption properties AB40 by prepared , /SBA-16 /rGO catalysts were examined. successful synthesis such was affirmed results FE-SEM, EDX, TEM, FTIR, XRD nitrogen measurements. followed Langmuir model, with maximum capacities 169.2, 21.1 16.6 mg/g /rGO, respectively. result explained based specific surface areas. decolorization efficiency estimated through several factors, including initial concentration, pH H 2 concentration. disclosed that catalyst dose = 1 g/L, concentration 50 mg/L, [H ] 15 mmol/L optimum conditions full within 60 min at 35 °C.

In recent years, the persistence of pharmaceutical contaminants like metronidazole (MNZ) and penicillin G (PG) in water bodies has become a major environmental concern. The present research studied simultaneous degradation MNZ PG utilizing an AgZnFe2O4@Ch catalyst generated through co-precipitation technique as effective stimulator for persulfate (PS) existence UV light. structure was characterized using X-ray powder diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy, vibrating-sample magnetometer, energy dispersive spectroscopy mapping. After 50 minutes reaction time under ideal operating conditions, which included 0.4 g/L catalyst, 4 mM PS, 5 mg/L PG, pH 5, highest 81.5 % 82.3 were obtained. Statistical parameters, including R2 values 0.985 0.981 indicate very good agreement between predicted observed values.
