TiO_(2)基油水分离膜的合成及其在油水分离中的应用

The synthesis and application of TiO_(2)-based membrane in oil-water separation

含油污水进入水环境不仅会污染水体资源,而且还会造成一定的经济损失.传统的油水分离处理技术通常需要花费较长的时间且分离不完全.TiO_(2)具有稳定、无毒、廉价等优点且被认为是一种具有“自清洁”功能的半导体材料,以其为基体构建的TiO_(2)基油水分离膜具有卓越的自清洁能力和油水分离性能,成为构建超强抗污油水分离膜的热点材料之一.本文从TiO_(2)基油水分离膜的合成、性能及应用展开综述,重点讨论了提升TiO_(2)基油水分离膜油水分离性能和可见光响应性的技术优化手段.

A large amount of oily sewage entering the water environment will not only pollute the water resources,but also cause the economic losses.The traditional methods for oil-water separation usually take a long time and the separation is incomplete.TiO_(2) has the advantages of stable,non-toxic,cheap and it is believed as the self-cleaning semiconductor.The TiO_(2)-based oil-water separation membrane exhibits the excellent abilities of self-cleaning and oil-water separation,which is a hot material for the construction of super-fouling-resistant membrane.In this paper,the synthesis,performance and application of TiO_(2)-based oil-water separation membrane was reviewed,and the technical optimization means for improving the performances of oil-water separation and visible light response of the membranes were mainly discussed.
