Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
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.
