钌和铱阳极在环境电化学中的应用现状

Application status of ruthenium and iridium anodes in environmental electrochemistry

贵金属阳极,特别是含有钌或铱的金属复合氧化物(MMO),由于其优异的导电性和较少的溶解性,在处理工业废水领域已引起人们的广泛关注。随着新型电极材料制备技术的发展,贵金属是目前电化处理工业污水方面最有前景的阳极材料之一。基于对70多篇文献的分析,本文详述了贵金属阳极材料在降解染料污水、工业废水、医药、农药残留等有机污染物的应用。

Noble metal anodes,especially metal mixed oxides(MMO)containing Ru or Ir oxides,due to its superior conductivity and sparingly soluble characteristics,has attracted numerous attentions in the field of treatment of refractory industrial wastewater.With the development of the preparative technology of new electrode materials,noble metal seems to be one of the most promising anode materials for the electrochemical treatment of industrial effluents.Based on the analysis of more than 70 literatures,the application of noble metal anode materials in the degradation of organic pollutants is described in detail such as dyestuff effluents,industrial wastewater,medicine and pesticide residues.
