| 摘 要： | 在气-液两相混合物中进行高压脉冲介质阻挡放电产生非平衡等离子体,以罗丹明B水溶液为模拟废水处理对象,考察了不同因素对降解效果的影响.实验结果表明：提高脉冲电压峰值和脉冲频率及延长放电时间均可提高罗丹明B的去除率;溶液初始pH值的提高,对于降解效率影响不大;溶液初始质量浓度提高时,罗丹明B的降解率（百分比）降低,但是降解...

| Abstract: | A non-thermal plasma processing system was established by means of high-voltage pulsed dielectric barrier discharge in liquid-gas medium.Rhodamine B solution was chosen as the target pollutant and the degradation rates under different experimental conditions were investigated.The obtained results showed that the removal rate of Rhodamine B could be improved either by increasing the peak voltage and frequency of the pulse or by increasing the discharge time.The initial pH value of the solution had little eff... |
