摘要
基于光催化氧化技术在处理难降解有机物方面的优势,着重阐述了紫外光活化不同催化剂/氧化剂降解安赛蜜的机理、效能和影响因素。同时,从降解效果、催化氧化副产物和后续降解能力等方面对不同光催化氧化技术进行归纳比较,总结了单一自由基的不稳定性,是后续降解能力不足的关键,从而导致处理过程中可能产生的有毒副产物得不到进一步氧化。最后,对不同自由基之间的协同作用进行了展望。
Based on the advantages of photocatalytic oxidation technology in the treatment of refractory organic matter, the mechanism, efficiency and influencing factors of the degradation of acesea honey by different catalysts/oxidants under UV activation were discussed.At the same time, different photocatalytic oxidation technologies were compared from the aspects of degradation effect, catalytic oxidation by-products and subsequent degradation capacity, etc.It was concluded that the instability of single free radical is the key to the insufficient subsequent degradation capacity, thus leading to the failure of further oxidation of the toxic by-products that may be produced in the treatment process.Finally, the synergies between different free radicals were prospected.
