摘要: 为了去除难降解的酚类物质,本文以活性碳纤维负载钴酞菁(CoPc-ACF)为催化剂、以H2O2为氧化剂组成催化氧化体系(CoPc-ACF/H2O2)对4-NP、4-MP和取代氯酚进行吸附催化氧化去除。该体系充分发挥了CoPc-ACF中活性碳纤维的吸附性能和钴酞菁的催化性能。CoPc-ACF用量为0.4g, 双氧水用量为100mmol/L、取代酚浓度为0.2-0.5 mmol/L,25 ℃反应5h后用UPLC检测酚类物质的催化氧化效果,结果表明几种取代酚的催化氧化剩余率均小于3%, 取代基种类和个数对催化氧化过程的影响不大。采用GC/MS对比分析了不同取代酚催化氧化后产物,提出了可能的反应机理。

Abstract: In order to remove refractory phenolics, activated carbon fibers supported cobalt phthalocyanine combined with H2O2 as a catalytic oxidation system to catalytic degradation of substituted phenols was studied. The adsorption of ACF and the catalysis of cobalt phthalocyanine were brought into fullest play in this system. The effect of catalytic oxidation was analyzed by UPLC after 5h reaction which under the condition of CoPc-ACF 0.4g, H2O2 100 mmol/L, 25 oC and substituted phenols from 0.2 mmol/L to 0.5mmol/L. The results showed that surplus rate of phenols were under 3%, the kind and number of substitutent group has little effect on catalytic oxidation. The by-products formed in the catalytic oxidation of substituted phenols were identified by GC-MS methods. Catalytic oxidation degradation mechanism of substituted phenols by CoPc-ACF/ H2O2 was proposed
