摘要
介绍了改性TiO_2对重金属离子光催化去除机制,以及离子掺杂、复合和表面功能化等改性方法,探讨了有机电子给体、无机离子和气氛等因素对改性TiO_2光催化去除Cr(Ⅵ)、Pb(Ⅱ)、Hg(Ⅱ)、U(Ⅵ)及As(Ⅴ)等有毒离子的影响,展望了改性TiO_2在光催化去除重金属离子中的应用前景。
The photocatalytic mechanism on removal of heavy metal ions in waste solution by TiO2-modified and the modification methods of TiO2 such as element doping,recombination and surface functionalization are introduced.The effects of organic electron donor,co-existing inorganic ions and gas atmosphere on removal of Cr（Ⅵ）and Pb（Ⅱ）,U（Ⅵ）and As（Ⅴ）in waste solution with TiO2-modified are comprehensively discussed.The utilization prospect of the TiO2-modified for photocatalytic removal of heavy metal ions is prospected.
