Globalization has increased production in various industries, including textiles, food, and pharmaceuticals. These industries employ different dyes production, leading to undesired discharge, which conventional treatment fails remove from the water. The present study aims synthesize, characterize, use pure catalysts (TiO2 Zn2SnO4) their compounds doped with CoFe2O4 together ozone (O3) for degradation of azo dye yellow tartrazine (TZ), evaluating process. For this characterization, N2 porosimeter, zeta potential, X-ray diffraction, SEM-EDS, diffuse reflectance spectra were used. Specific surface areas (m2 g−1) 109, 106, 65, 83 used TiO2, CoFe2O4/TiO2, Zn2SnO4, CoFe2O4/Zn2SnO4, respectively. Both are characterized as nanocatalysts they have a band gap 2.75 2.83 eV average particle size 98 85 nm CoFe2O4/TiO2 We employed reactional model, was able describe catalytic ozonation all cases, low R2 0.9731. combination processes TZ 57% 74% compared O3 alone, achieving maximum 98.5% within 50 min catalysis at flow rate. This highlights potential produced energy-efficient effluent treatment.

Advanced oxidation processes are one of the effective means for degrading tetracycline hydrochloride (TCH) in water. Using pickling iron sludge as raw material, an sludge-based catalyst was prepared through a two-step hydrothermal method, and catalyst/persulfate system established to degrade TCH Experimental data show that exhibits high efficiency degradation. This experiment demonstrates simple modification can be transformed into low-cost, high-efficiency catalyst.
