| 摘 要： | 采用水热法制备了GO/Fe_3O_4/ZnO复合材料,并用SEM、FT-IR、XRD等手段对其进行了表征。以苯酚为降解目标,探讨了GO/Fe_3O_4/ZnO复合材料用量、H_2O_2投加量、苯酚浓度和pH等因素对降解苯酚效果的影响。实验结果表明,在GO/Fe_3O_4/ZnO投加量为200 mg/L,H_2O_2投加量为12 mmol/L,pH=7.2的条件下,利用该复合材料对苯酚质量浓度为88.85 mg/L的油田污水进行光催化Fenton降解,60 min后,苯酚降解率可达98%。

| Abstract: | The composite material GO/Fe3O4/ZnO has been prepared by hydrothermal method,and characterized by SEM,XRD and FT-IR. Having phenol as the degradation target,the influences of the factors,such as the dosages of the composite material GO/Fe3O4/ZnO,and H2O2,the concentration of phenol,the pH,etc. on the degradation effect of phenol are discussed. The experimental results show that using the composite materials ,under the following conditions:the GO/Fe3O4/ZnO dosage is 200 mg/L,H2O2 dosage 12 mmol/L,and pH=7.2,88.85 mg/L of oilfield wastewater is treated by the photo?catalysis Fenton degradation process. 60 min later,the phenol degradation rate can reach 98%. |
