The persistence and toxicity of synthetic dyes in aquatic environments demand innovative and sustainable treatment solutions. This study investigates the photocatalytic degradation of tartrazine using an activated carbon-supported BiFeO3 (AC/BFO) composite under visible light. The AC/BFO catalyst was characterized using SEM, BET, XRD and FT-IR analyses to confirm its structural and chemical properties. Key reaction parameters, including catalyst loading, hydrogen peroxide concentration, and pH, were optimized to maximize degradation efficiency. The results revealed that a catalyst loading of 0.2 g/L, 10 mM hydrogen peroxide, and pH 3 achieved the highest degradation rate. These findings highlight the potential of AC/BFO composites as effective photocatalysts for dye-laden wastewater treatment, contributing to the advancement of green and sustainable remediation technologies.
