纳米二氧化钛处理含汞废水技术研究进展

Advances in Treatment of Wastewater Containing Mercury by Titanium Dioxide Nanomaterials

综述了纳米TiO2处理含汞废水的研究现状,分析了其吸附和光催化处理Hg(Ⅱ)的影响因素及存在的问题,以期为进一步提高纳米TiO2的除汞效率及其吸附-光催化技术在含汞废水处理中的应用提供基础.

With the continuous development of nanotechnology,the property of nano-TiO2 will find ever-increasing wider application,for instance,in the field of pollutant treatment.After a literature review of the current situation in aspects of the mercury-containing wastewater treatment by nano-TiO2,and analysis is made of its adsorption,the influencing factors in the photocatalytic treatment of Hg（II）and the existing problems in hope of improving the mercury removal efficiency and increasing the use of the adsorption-photocatalytic technology for mercury containing wastewater treatment.
