摘要:

采用浸渍法制备Fe2O3/γ-Al2O3催化剂,利用扫描电镜(SEM)、X射线衍射仪(XRD)、X射线光电子能谱仪(XPS)对催化剂进行了表观形貌、晶体结构、表面元素组成的分析,并将其用于降解苯酚的非均相Fenton反应体系。在有UV与无UV条件下,通过对质量浓度为250 mg/L的苯酚废水降解效果的考察优化催化剂制备条件及反应条件。实验结果表明,UV条件下的降解速率明显高于无UV条件,2种条件下苯酚降解2 h后降解率分别最高能达到89.4%、94.7%。

Abstract:

Fe2O3/γ-Al2O3 catalysts have been prepared by impregnation process,and their apparent form,crystal structure and surface element are analyzed by powder X-ray diffraction(XRD),scanning electron microscopy(SEM), and X-ray photoelectron spectroscopy(XPS).With and without UV conditions,the preparation conditions and reaction conditions of catalysts are optimized by the degradation efficiency of phenol,whose concentration is 250 mg/L.The results show that with UV condition,the degradation rate is obviously higher than that without UV condition.With two kinds of conditions,the degradation rate of phenol can reach 89.4% and 94.7% respectively,two hours later.

Key words: heterogeneous catalysis, Fenton, Fe2O3/γ-Al2O3, UV
