Abstract
Background and Purpose: Untreated dye-containing wastewater poses severe environmental hazards due to the persistence, toxicity, and resistance to biodegradation of dyes. This study aimed to evaluate the efficiency of catalytic ozonation using calcium peroxide (CaO₂) and titanium dioxide (TiO₂) to remove Acid Brown 14 from aqueous solutions.
Materials and Methods: Laboratory-scale experiments were performed using a batch ozonation reactor. The influence of catalyst dosage, initial dye concentration, pH, and contact time on removal efficiency was assessed. Chemical oxygen demand (COD) was measured to evaluate dye degradation. Dye concentration was determined spectrophotometrically at 461 nm.
Results: Optimal removal of Acid Brown 14 was achieved at pH 9, a contact time of 60 minutes, an initial dye concentration of 50 mg/L, and a catalyst dose of 0.4 g/L, resulting in a decolorization efficiency of 97.25%. Under these conditions, COD removal efficiency reached 58.9% after 60 minutes.
Conclusion: The findings confirm that CaO₂ and TiO₂ exhibit high catalytic activity in the ozonation process and represent promising agents for decolorising textile wastewater.
