| 摘 要： | 采用低温真空冷冻干燥方法，以FeSO4和Na2S为原料合成了含NaFe2OH(SO3)2·H2O、FeS和FeS2等主要成分的复合物芬顿催化剂，采用X射线衍射(XRD)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对材料进行了表征，并以苯酚为目标污染物，研究该催化剂对苯酚的催化降解性能. 结果表明:在催化剂投加质量浓度为0.3 g/L，H2O2初始浓度为50 mmol/L和pH为4.0的条件下，1 g/L的苯酚在反应30 min时的去除率为97%. 这说明该芬顿催化剂对高质量浓度苯酚的去除性能良好，在有机污染物的去除领域具有重要的应用前景.

| Abstract: | FeSO4 and Na2S were synthesized into a composite Fenton catalyst with low temperature vacuum freeze-drying. It is composed of NaFe2OH(SO3)2·H2O, FeS and FeS2. The composite was characterized with XRD and XPS. Then phenol was used as the target organic pollutant to study the composite's catalytic degradation of it. The results showed that the removal rate of phenol reached 97% after 30 min degradation under the conditions of 1 g/L phenol, 0.3 g/L catalyst, 50 mmol/L H2O2 and pH 4.0, indicating that the Fenton catalyst had a good performance in the removal of high-concentration phenol. This composite can have a good prospect of application in organic pollutant removal. |
