【摘要】 论述了稀土在各种废水处理过程中发挥的强化催化作用。研究表明,掺杂稀土化合物能降低 TiO₂能带宽度从而可使 TiO₂光解材料在太阳光下分解水中有机物成为可能,也有望提高 TiO₂/O₃/Uv 的废水处理能力;指出 TiO₂/O₃/UV/RE 应作为未来一段时期废水处理技术发展的重点。更多还原

【Abstract】 It was discussed by the numbers that a rare earth（RE）compound exerts an aggrandizement effect on catalytic/assistant-catalytic degradation in sewage disposal process.Especially,it was stressed that the fact have wildly caught people eyes that RE can enable the catalyst TiO₂ to decompose organisms of effluent in visible light such as sunlight due to decrease of the energy band width of TiO₂.Finally it was suggested that TiO₂/O₃/UV/RE intermingling RE should be put in the development emphases of purification technology of aqueous environment at some length of the future time.更多还原
