摘要
综述了过硫酸盐(PS)和过氧单硫酸盐(PMS)的活化方法及机理,以及基于PS和PMS开展的烟气多污染物脱除研究和建立的脱除方法。PS和PMS可通过过渡金属、加热、紫外光、超声波和碳基材料等活化产生硫酸根自由基,具有强氧化性,可去除多种烟气污染物。另外对比分析了PS和PMS在烟气污染物脱除中的优势与不足,并对PS和PMS应用于燃煤烟气污染物脱除行业进行了展望。
The activation methods and mechanism of persulfate(PS)and peroxymonosulphate(PMS)were reviewed,as well as the research and established removal methods of multi pollutants in flue gas based on PS and PMS.PS and PMS can be activated by transition metal,heating,UV,ultrasonic and carbon based materials to produce sulfate radical,which has strong oxidizability and can remove a variety of flue gas pollutants.In addition,the advantages and disadvantages of PS and PMS in flue gas pollutant removal are compared and analyzed,and the application of PS and PMS in coal-fired flue gas pollutant removal industry is prospected.
