摘要
纳米TiO2粒径小、无毒、光催化、比表面积大、吸收性能好,在污水处理领域有广泛的应用前景.从吸附和光催化作用两个方面综合描述了纳米TiO2在污水处理中的应用.纳米TiO2对Cr、As、Pb等有很好的吸附效果,对有机磷农药、活性染料、石油污染物、表面活性剂、汞、氰化物、亚硝酸盐等有很好的光催化效果.
Nanoparticles-TiO2 has broad application prospects in the field of sewage treatment ,because of its small size,non-toxicity,big specific surface area,photocatalysis and good absorption performance .In this paper ,the application of TiO 2 nanoparticles in wastewater treatment is discussed from adsorption and photocatalysis.Nano-TiO2 has a good effect on the adsorption of Cr ,As,and lead.TiO2 nanoparticles have a very good photocatalytic effect on the organophosphorus pesticides ,dyes,oil pollution,surfactants,mer-cury,cyanide,nitrite.
