Preparation of Prussian blue analogues and their application for catalytic activation of Peroxymonosulfate
碩士 === 國立中興大學 === 環境工程學系所 === 104 === In this study, we evaluated Prussian blue analogues (PBAs) as catalysts to activate peroxymonosulfate (PMS) which generates sulfate radicals to degrade a toxic dye, Rhodamine B (RhB). The results show that Co and Mn-containing PBAs were capable of activating PB...

The results show that Co and Mn-containing PBAs were capable of activating PBAs while Cu, Fe and Ni-containing PBAs were almost unable to activate PMS. Among all PBAs, Co3[Fe(CN)6]2 (Co-Fe) and Co3[Co(CN)6]2 (Co-Co) were proven as the most effective catalysts for PMS activation. Factors influencing RhB decolorization were further investigated to examine PMS activation by Co-Fe and Co-Co under various conditions, including changes of PBA loading, PMS dosage, temperature and pH. The results show that both of Co-Fe and Co-Co exhibited much higher catalytic activities than Co3O4 for activating PMS to degrade RhB in water, indicating that Co-containing PBAs is a promising catalyst. The preferred operating conditions for PMS activation by Co-Fe and Co-Co were at high temperatures and neutral conditions. Effects of radical scavengers on degradation suggest that RhB degradation using PMS activated by Co-Fe and Co-Co both primarily involved sulfate radicals and hydroxyl radicals to a lesser extent. Recyclabilities of both Co-Fe and Co-Co were stable and effective for activating PMS over multiple cycles. In summary, Co-containing PBAs are promising catalysts to activate PMS for degradation of organic pollutants. 林坤儀 2016 學位論文 ; thesis 73 zh-TW |
