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

College of Urban Construction, Nanjing Tech University, Nanjing 211816, China

摘要

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。

Abstract: In this paper, the degradation effect of heterogeneous activating peroxydisulfate and peroxymonosulfate by GAC on the azo dye AO Ⅱ in water were studied. The effects of persulfate dosage, activated carbon dosage, solution pH and inorganic anion on the degradation rate of AO Ⅱ were investigated. The reasons for the difference in the degradation of dyes by different persulfates were studied. When the azo dye concentration was 20 mg/L and the molar ratio of persulfate to acid orange Ⅱ was 200∶1, the degradation rate of dyes was the highest. Degradation effect got better when adding peroxydisulfate, and the solution was in acidic condition, and the increase of granular activated carbon was conductive to the removal of dyes; the addition of inorganic anions had an inhibitory effect on degradation of AO Ⅱ; free radicals generated on the surface of activated carbon played an important role in the degradation of dye.
