| 摘 要： | 采用多针-水电极反应器,研究了直流电晕放电对活性艳蓝KN-R染料废水的脱色,考察了放电电压、初始pH值和初始浓度对活性艳蓝脱色的影响,通过对液相活性物质(O3和.OH)浓度的考察探讨了脱色机理.结果表明,多针-水电极直流电晕放电对活性艳蓝脱色效果明显;放电电压、溶液初始pH值对活性艳蓝脱色效果的影响与其对液相O和.OH浓度的影响一致;.OH和O是促使RBB脱色的主要因素.

| Abstract: | The decoloration of Reactive Brilliant Blue KN-R(RBB)using a multi-needle-to-water DC corona discharge system was investigated.The effect of applied voltage,initial concentration and initial pH on RBB decoloration was studied.The mechanism of decoloration was discussed by investigating the changes of O_3 and ·OH quantities in aqueous.The results show that multi-needle-to-water DC corona discharge could decolor RBB efficiently.O_3 and·OH were the main factors to decolor RBB. |
