摘要
二氧化硫的电化学处理技术应用领域非常广泛,具有几乎不需要化学试剂,能耗低,环保等优点,对其研究具有重要意义。介绍了二氧化硫电化学处理的两个方向,即电化学还原和电化学氧化。电化学还原法主要是将二氧化硫还原成硫磺或者连二亚硫酸盐;电化学氧化法主要是将二氧化硫氧化成硫酸。并从这两个方面系统介绍了国内外的研究情况和发展趋势。
Sulfur dioxide electrochemical treatment technology is widely used in many fields with the advantages of almost no chemical reagent,low energy consumption,green and so on,which is of significance to study.Two directions of electrochemical treatment of sulfur dioxide,i.e.,electrochemical reduction and electrochemical oxidation,were introduced.Electrochemical reduction method is mainly to reduce sulfur dioxide to sulphur or hydrosulfite.Electrochemical oxidation is mainly applied to oxidize sulfur dioxide into sulfuric acid.Research situation and development trend at home and abroad are systematically introduced.
