| 摘 要： | 采用柠檬酸盐溶胶-凝胶法制备了Fe/Ce/沸石负载型芬顿催化剂,通过透射电镜(TEM)和X射线衍射(XRD)对其进行表征,并将其作为非均相类芬顿催化剂处理孔雀石绿染料溶液。研究表明,通过掺杂Ce,可提高催化剂颗粒分散度和催化剂表面的氧气含量,进而提高催化活性。在催化剂投加量3.0 g/L,H2O2投加量67 mg/L,pH=8.0的条件下,反应30 min后,浓度为150 mg/L的孔雀石绿溶液脱色率可达97.3%。 |

| Abstract: | A supported Fe/Ce/zeolite Fenton-like catalyst was prepared by citrate sol-gel method and characterized by transmission electron microscope (TEM) and X-ray diffraction (XRD), then the catalyst was used as a heterogeneous Fenton catalyst for degradation of simulated malachite green solution. The results show that better dispersion of catalyst crystal can be achieved by adding Ce, and the content of chemisorbed oxygen can also increase on the surface of catalyst, so the catalyst activity can be enhanced. Under the following experimental conditions: catalysts dosage of 3.0 g/L,initial H2O2 dosage of 67 mg/L, pH of 8.0,for 150 mg/L malachite green solution, 97.3% of decolorization efficiency could be achieved in 30 min. |
| Keywords: | heterogeneous Fenton catalyst malachite green degradation |
