This study involved the synthesis of magnetite nanoparticles by co-precipitation method. The synthesized were subsequently evaluated for their catalytic efficacy in degradation and ozonation tartrazine dye (TTD), employing sodium persulfate as a catalyst both presence absence ozone. material characterization revealed that Fe3O4 proven to have crystalline structure XRD. While spherical agglomerates with flower-like morphology SEM, similarly FT-IR detected Fe – O H bond vibrations, boosting surface area activity. TTD was assessed laboratory-scale reactor, its progress monitored using UV-visible spectrophotometry. A comparative analysis two methods demonstrated superior compared degradation, achieving maximum 94.35% within 25 min contact time. Optimal parameters included concentration 50 ppm, dosage 0.75 g, 8 mm, ozone inlet 5 g/L at pH 3. Evaluation kinetics indicated second-order model most appropriate, suggesting physicochemical nature removal process. Furthermore, demonstrates enhanced efficiency decomposition conventional methods.
