湿式过氧化氢催化氧化降解喹啉及其机理
Quinoline degradation and mechanism in catalytic wet peroxide oxidation system
摘要
Abstract
In order to study the removal and degradation mechanism of quinoline in catalytic wet peroxide oxidation (CWPO) system, a series of experiments were conducted over CuO-FeOx/γ-Al2O3catalyst. The influence of reaction temperature, initial pH, dosage of H2O2 and amount of catalyst were investigated, and the role ofiOH and degradation pathways of quinoline were analyzed. CWPO had good removal efficiency for quinoline. A complete quinoline conversion and 88.34% total organic carbon (TOC) removal were achieved in 60 min with initial pH of 7, 29.15 mmol·L-1 of H2O2 and 4 g·L-1 of catalyst at 80℃.iOH oxidation played a dominant role in quinoline degradation in CWPO system, and its average production rate was 1.69×10-6 mmol·L-1·min-1. Under neutral and acidic conditions, quinoline degradation in CWPO system followed different pathways, and generated pyridine-based or benzene-based intermediate products.关键词
