摘要 采用共沉淀法制备了Fe-Cu-柱撑黏土,应用X射线衍射、扫描电镜及比表面积测定对其进行表征,并以4-氯酚废水为处理对象,对该材料催化H2O2氧化降解4-氯酚的影响因素进行了研究。结果表明:Fe和Cu已成功插入黏土层间,形成高活性及高稳定性的柱撑黏土催化剂,60 min内即可催化4-氯酚完全氧化降解,而且能够循环使用6次。实验获得的适宜反应条件为:c(4-CP)=2 mmol/L、c(H2O2)=30 mmol/L、ρ(催化剂)=1 g/L、pH为2.7~6.8、温度40℃、反应时间2 h。 Fe-Cu pillared clay has been prepared by co-precipitation method, and characterized by X-ray diffraction,scanning electron microscope,and specific surface area determination. Taking 4 -chlorophenol wastewater as the treatment object,the influencing factors of Fe-Cu pillared clay on the catalysis of H2O2 oxidation degradation of 4-chlorophenol (4-CP) are studied. The results show that iron and copper has been successfully intercalated to the interlayer of clay,forming highly active and stable pillared clay catalyst. Within 60 min the 4-chlorophenol oxidation and degradation can be catalyzed successfully,and can be recycled six times. The appropriate reaction conditions obtained from experiments are as follows:c(4-CP)=2 mmol/L,c(H2O2)=30 mmol/L,ρ(catalyst)=1 g/L,pH 2.7-6.8,temperature 40℃,and reaction time 2 h.
