摘要:
研究了光催化复合氧化技术对两种典型抗生素环丙沙星和磺胺甲恶唑的降解与矿化效果.用响应面法对所采用的复合氧化反应器进行运行条件优化,然后在优化所得的最优运行条件的基础上分别探究了pH值对CIP和SMX在该复合氧化体系中降解与矿化效果的影响.结果表明,降解受pH影响较小,CIP在中性条件下更易被矿化,SMX在酸性条件下更易被矿化.最后对CIP和SMX在该体系中降解所生成的中间产物进行抑菌活性分析,结果表明,水样中的抑菌活性分别在CIP和SMX的矿化率达到34.12%和13.04%时完全消失.
Abstract:Degradation and mineralization of two typical antibiotics, ciprofloxacin and sulfamethoxazole, by the combined photocatalysis and oxidation technology were investigated in this work.Firstly, the response surface method was used to optimize the operation conditions of the combined oxidation reactor used.Then,based on the operation conditions,the effects of pH on the degradation and mineralization of CIP and SMX were investigated.The results showed that the pH had little effect on the degradation, CIP was mineralized more easily under neutral conditions, and SMX was mineralized more easily under acidic conditions. Finally, the antibacterial activity of the intermediate products formed during the degradation of CIP and SMX was analyzed.The results showed that the antibacterial activity in the water samples completely disappeared when the mineralization rates of CIP and SMX reached 34.12% and 13.04%, respectively.
