| 摘 要： | 在不加任何助剂的情况下,等离子体发生器产生的高能粒子、臭氧以及紫外光的联合作用,可以有效地降解各类有机物.试验用介质阻挡放电等离子技术(DBD)对初始浓度40mg/L的雅格素红3BF进行脱色和降解处理5 min(放电间隙为10mm),雅格素红3BF的脱色率可以达到91.7％.随着处理时间的延长,首先是偶氮基团的破坏,随后是芳香类基团的降解.染液初始浓度越高,最终脱色率越低；放电间隙越窄,越有利于脱色.

| Abstract: | The combination effect of high-energy electron,ozone and ultraviolet light produced by dielectric barrier discharge plasma(DBD) generator can effectively degrade various kinds of organics at atmosphere without any other additives.The DBD technique is used for discoloration and degradation of Argazol Red 3BF.After plasma treatment of Argazol Red 3BF with initial concentration of 40 mg/L(discharge gap of 10 mm) for 5 min,the decolorization rate can reach 91.7%.Azo groups of the dye are broken firstly,and then the aromatic groups are degraded.The decolorization rate is decreased with the increase in initial concentration.The reduction of the discharge gap can greatly enhance the decoloration efficiency,but it is easy to cause security problems when the gap is too narrow. |
