  • 摘要: 通过亚铁离子活化过硫酸氢钾复合盐产生氧化性的硫酸根自由基，以吲哚美辛（IM）为目标污染物，研究了不同亚铁离子浓度和过硫酸氢钾浓度，以及加入Cl-离子和腐殖酸对吲哚美辛降解情况的影响。结果表明，[IM]：[PMS]：[Fe2+]=1：2：2条件下，IM的去除率接近100%；低浓度的Cl-抑制吲哚美辛的降解，高浓度则为促进作用；而腐殖酸都在不同程度上抑制了吲哚美辛的降解。经淬灭实验表明，亚铁离子活化过硫酸氢钾降解吲哚美辛中起主要作用的自由基是SO4-·。该方法能在短时间内高效降解吲哚美辛，为实际废水中吲哚美辛去除提供参考。
    Abstract: The degradation of indomethacin (IM) by the ferrous-ion-activated sodium peroxymonosulfate (PMS) was investigated.This process is based on the generation of sulfate radicals,which are powerful oxidizing species in aqueous phase.The effects of varying concentrations of Fe2+ and PMS and the addition of Cl- and humic acid (HA) on the degradation efficiencies of IM were studied.The results showed that the removal of IM was close to 100% at the molar ratio of [IM]:[PMS]:[Fe2+]=1:2:2.A low concentration of Cl- had a negative effect and a high concentration of Cl- had a positive effect on the degradation of IM,whereas HA had a negative effect.The results of quenching experiments revealed that SO4-· was the major active radical that contributed to the degradation of IM by ferrous-ion-activated peroxymonosulfate.This method could efficiently degrade IM in a short time,which could help in the treatment of actual wastewater contaminated by IM.
