Three cheap DESs comprising of -methyldiethanolamine (MDEA) and imidazole (Im), 1,2,4-triazole, and tetrazole were investigated for capturing SO at low concentrations. Surprisingly, with the addition of Im, the SO absorption capacity and desorption efficiency were improved. Spectroscopic analysis and quantum chemical calculations confirmed that MDEA-Im effectively and reversibly captured SO through the hydrogen bond network and synergistic action between MDEA and Im.
研究了三种由N-甲基二乙醇胺（MDEA）与咪唑（Im）、1,2,4-三唑和四唑组成的廉价深度共熔溶剂（DESs）用于低浓度SO₂捕集。令人惊讶的是，添加Im后，SO₂吸收容量和解吸效率得到了提高。光谱分析和量子化学计算证实，MDEA-Im通过氢键网络以及MDEA与Im之间的协同作用有效地、可逆地捕集了SO₂。
