Bromate by-products of bromate oxidation are widely concerned because of its carcinogenicity. There are many treatments such as physics, chemistry and biology. Among them, the photocatalytic removal technology is energy-saving and environmental-friendly due to its sunlight-based, and the reaction conditions Mild and so has gradually become a research hot spot. Based on the analysis of the mechanism of photocatalytic removal of bromate, the research progress on the photocatalytic removal of bromate by titanium dioxide is described, and the main influencing factors are discussed. The research prospects of photocatalytic technology in this field are prospected.
