利用室温合成和高温热解法制备了不同负载量的CuO/CN非均相催化剂,用于活化过一硫酸盐(p.S)降解四环素(TC)。通过傅里叶变换红外光谱仪(FT-IR)、扫描电子显微镜(SEM)、能量色散X射线荧光光谱仪(EDS)、X射线粉末衍射仪(XRD)等表征仪器对材料进行了详细表征,评价了Cu O/CN材料的表面形貌和物质状态。结果表明,铜以Cu O的形式均匀地负载在CN上,并对p.S降解四环素表现出高效的催化性能。在四环素初始质量浓度为20 mg/l.p.h.5.5、p.S浓度为0.3 mmol.l.2.5%Cu O/CN投加量为0.2 g/l.条件下,处理120 min后TC降解率达93.72%。采用猝灭实验和电子自旋共振(Ep.)技术分析降解过程的活性物质,结果表明^(1)O_(2)是TC降解过程的主要活性物种。催化剂历经5次循环实验后,TC降解率仍能够达到86.39%,表明催化剂具有较好的稳定性和重复使用性。因此,CuO/CN在催化p.S降解TC等抗生素方面具有良好的应用前景。
