| 摘 要： | 采用正交试验考察初始pH值、铁屑投加量及超声波功率对超声波协同零价铁降解硝基苯的影响大小及确定最佳反应条件,并探讨了降解过程的动力学规律.结果表明,降解率随铁屑投加量及超声波功率的增加而增大,随初始pH值的增加而变化不大.超声波与零价铁联用降解硝基苯具有明显的协同作用,协同因子为4.96,且降解过程符合拟一级反应动力学...

| Abstract: | The effects of initional pH、iron dosage and ultrasound power were inspected by orthogonal experiment in order to determined the order of impact and fixed the best reaction conditions,and the degradation kinetics was discussed.The results show that the degradation rate increases with the increase of iron dosage and ultrasound power,and little change with the increase of initional pH.The synergetic effect of ultrasound combined with zero-valent iron is significant,cofactor is 4.96.The degradation accord with the pseudo-first-order reaction kinetics law. |
