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%.

摘要：

采用水热法制备了GO/Fe₃O₄/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/Fe₃O₄/ZnO复合材料用量、H₂O₂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/Fe₃O₄/ZnO投加量为200 mg/L，H₂O₂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%。
