摘　　要：利用共沉淀法制备Cu-Mn-Ce/海泡石催化剂,利用XRD、TEM和BET等表征其物化性质,进一步构建非均相催化臭氧氧化体系。探讨了不同实验条件下布洛芬废水的去除效率。得到的最优反应条件为:Cu-Mn-Ce负载量为20%、臭氧通量为30 mg/min、催化剂添加质量为0.45 g、p H=7,此时,布洛芬废水TOC的去除率可达96.17%。循环实验表明,催化剂重复利用5次后,降解效率仍为93.28%,表明催化剂重复利用性能良好。Coprecipitation method is employed to prepare Cu-Mn-Ce/sepiolite catalyst with sepiolite as carrier.XRD,TEM and BET characterization are carried out to explore the physicochemical properties of the catalyst.On this basis,a heterogeneous catalytic ozonation system is constructed to treat with ibuprofen wastewater.The removal effect of ibuprofen wastewater by the catalyst is explored under different single-factor conditions.The optimum reaction conditions are gained as follows:the load of Cu-Mn-Ce is 20%,the mass flow of ozone is 30 mg·min-1,the dosage of the catalyst is0.45 g,and initial solution p H=7.Under these optimum conditions,the removal rate of TOC in ibuprofen wastewater can reach 96.17%.The catalytic degradation efficiency of Cu-Mn-Ce/sepiolite can still reach 93.28%after five cycles,indicating a good reusability.
