| 中文摘要 | 由於羥基化二苯甲酮 (HBPs) 是最典型的紫外線過濾劑和紫外線穩定劑，因此越來越多的 HBPs 釋放到水生環境中，對水生生態造成了嚴重威脅。在各種 HBP 中，4,4'-二羥基二苯甲酮 (4HBP) 作為一種新興污染物，由於其內分泌干擾作用的潛在毒性而受到越來越多的關注。為了建立從水中去除 4HBP 的有用技術，作為第一項研究，本研究旨在開發硫化鈷作為多相催化劑，以激活單過硫酸鹽 (MPS) 以生成硫酸根 (SO4 •−) 以降解 4HBP。特別是，通過簡單硫化 Co3[Co(CN)6]2 形式的普魯士藍 (PB) 將這種 PB 轉化為 CSNF，開發了獨特的硫化鈷納米膜 (CSNF) 立方組裝。這樣得到的 CSNF 表現出比原始 PB 和參考催化劑 Co3O4 高得多的催化活性，用於活化 MPS 以在降解程度和動力學方面降解 4HBP。在 CSNF = 50 mg/L 和 MPS = 100 mg/L 的極低劑量下，可以在 15 分鐘內完全消除 5 mg/L 的 4HBP，證實 CSNF 是將 MPS 活化為 4HBP 的有前途的催化劑。 CSNF 激活的 MPS 降解 4HBP 的 Ea 也確定為 68 kJ/mol。分別使用電順磁共振和質譜儀研究了 CSNF 激活的 MPS 降解 4HBP 的激活機制和降解途徑，以進一步深入了解降解行為，以開發基於硫酸根的 4HBP 降解的最佳高級氧化過程。 |
| 英文摘要 | As hydroxylated benzophenones (HBPs) represent most typical UV filters and UV stabilizers, increasing release of HBPs into the aquatic environment has caused serious threats to the aquatic ecology. Among various HBPs, 4,4′-Dihydroxybenzophenone (4HBP) receives growing attentions as an emerging contaminant due to its potential toxicity of endocrine disrupting effect. For establishing useful techniques to remove 4HBP from water, this study, as the first study, aims to develop cobalt sulfide as a heterogeneous catalyst to activate monopersulfate (MPS) for generating sulfate radical (SO4•−) to degrade 4HBP. Especially, a unique cubic assembly of cobalt sulfide nanofilms (CSNF) is developed through a simple sulfurization of Prussian Blue (PB) in the form of Co3[Co(CN)6]2 to transform this PB to CSNF. Such a resulting CSNF exhibits much higher catalytic activities than the pristine PB, and the reference catalyst, Co3O4, for activating MPS to degrade 4HBP in terms of degradation extents and kinetics. With very low dosages of CSNF = 50 mg/L and MPS = 100 mg/L, 5 mg/L of 4HBP could be fully eliminated in 15 min, validating that CSNF is a promising catalyst for activating MPS to 4HBP. Ea of 4HBP degradation by CSNF-activated MPS is also determined as 68 kJ/mol. The activation mechanism and degradation pathway of 4HBP degradation by CSNF-activated MPS is investigated using electro paramagnetic resonance and mass spectrometer, respectively, to further to provide insights into degradation behaviors for developing optimal sulfate-radical-based advanced oxidation processes of 4HBP degradation. |
