  • 摘要: 为了提高等离子放电对染料的降解效率,研究了Fenton-like/TiO2耦合催化介质阻挡放电体系对活性艳蓝(X-BR)的脱色效果及降解机理。结果表明,投加Fe2+ 或Fe3+与TiO2组成的耦合催化体系可以显著提高X-BR的脱色率。反应10 min后,紫外可见扫描光谱和阴离子(Cl-、NO3-、SO42-)产量分析表明,介质阻挡放电体系可以有效破环蒽醌发色基团,耦合催化体系不仅强化了蒽醌结构的破坏,同时更加有效地破坏了苯环和萘环结构从而提高了TOC降解率。最后,比较研究了投加Mn2+ 和Cu2+对X-BR的脱色效果,在投加浓度均为0.5 mmol/L条件下,两者对X-BR的脱色起到抑制作用,因此,两者不适合作为耦合催化介质阻挡放电体系的添加离子。
    Abstract: The decomposition of reactive brilliant blue by dielectric barrier discharge, combined with Fenton-like TiO2, was investigated in order to improve the efficiency. Fe2+ or Fe3+, coupled with TiO2 was introduced in the discharge system, could enhance the discoloration effectively. After 10 min of treatment, the UV-VIS and IC analyses revealed that the discharge destroyed anthraquinones, while the coupled system destroyed benzene and naphthalene, thereby improving the TOC removal rate. Introduction of 0.5 mmol/L Mn2+ and Cu2+ revealed an inhibition effect on the discoloration, showing the unsuitability of these two ions for this process.
