ACTIVATED CARBON HETEROGENEOUS ACTIVATION OF DIFFERENT PERSULFATES TO DEGRADATION AZO DYE ACID ORANGE Ⅱ

  • 摘要: 研究了颗粒活性炭非均相活化过二硫酸盐和过一硫酸盐对水中偶氮染料酸性橙Ⅱ的降解效果。考察了过硫酸盐投加量、活性炭投加量、溶液初始pH值和无机阴离子对酸性橙Ⅱ降解率的影响,探究了不同过硫酸盐对染料降解效果差别的原因。结果表明:投加过二硫酸盐比过一硫酸盐的效果更好,偶氮染料浓度为20 mg/L,溶液中过n(PS)∶n(AOⅡ)为200∶1时降解率最高;颗粒活性炭投加量的增加有利于染料的去除,溶液处于酸性条件下染料降解率高于碱性条件,无机阴离子对酸性橙Ⅱ降解有抑制作用,产生于活性炭表面的自由基对染料的降解具有重要作用。
