摘要/Abstract

摘要：

采用微波强化催化湿式H₂O₂氧化法降解喹啉，以负载型Cu-Ce/γ-Al₂O₃/TiO₂为催化剂，考察了微波功率、反应温度、H₂O₂投加量和溶液初始pH对降解效果的影响。实验结果表明，在喹啉初始质量浓度为100 mg/L、微波功率为500 W、反应温度为60℃、pH=6、H₂O₂投加量为0.094 mol/L的条件下，反应18 min后，喹啉和TOC去除率分别可达100%、82.18%。微波可明显提高反应速率，反应体系中喹啉降解和H₂O₂分解均符合一级动力学。

Abstract:

Microwave-enhanced catalytic wet peroxide oxidation method has been applied to the degradation of quinoline,using immobilized Cu-Ce/γ-Al₂O₃/TiO₂ as catalyst. The influences of microwave power,reaction temperature,H₂O₂ dosage and initial pH on the degradation effect are investigated. The experiment results show that under the following conditions:quinoline initial mass concentration is 100 mg/L,microwave power 500 W,reaction temperature 60℃,initial pH=6,and H₂O₂ dosage 0.094 mol/L,after having reacted for 18 min,the removing rates of quino-line and TOC can reach 100% and 82.18%,respectively. Microwave can significantly improve the reaction rates. Both of the degradation of quinoline and decomposition of H₂O₂ in the reaction system conform with the first-order kinetics.
