Porous nano-TiO₂ prepared by the sol-gel technology was coupled with Fe₃O₄ which is magnetic material prepared by marinating-calcining method to afford the magnetic porous coupling Fe₃O₄/TiO₂ photocatalyst, the title compound was characterized. In this paper, we investigated the degradation to the bromamine acid solution under the fluorescent light and the effects of different adulterant proportion of Fe₃O₄ and calcining temperature to the degradation performance. The effects of the different dosages of photocatalyst were also discussed. The results show that when Fe₃O₄ adulterant proportion(molar ratio) is 5%, calcining temperature is 500°C and the dosage is 4g/L, the removal rates of chroma and total organic carbon to bromamine acid solution reached 98.35% and 80.69% respectively.
