摘 要: 乙二醇及乙二醇水溶液对SO2表现出较强的吸收和解吸性能,特别是在298.15 K下,体积分数为80%乙二醇水溶液对SO2的吸收和解吸能力最强。文中力图通过现代光谱技术手段研究乙二醇及乙二醇水溶液对低体积分数SO2的吸收机理。在体积分数80%乙二醇水溶液吸收SO2的过程中,UV,FTIR,荧光光谱结果表明,乙二醇和SO2的相互作用主要是分子间氢键及S…O配位作用,此类相互作用键力较弱,但有利于SO2的吸收和以SO2形式的解吸。 Ethylene glycol(EG) and ethylene glycol aqueous solution(EGW) with volume fraction 80% own strong capabilities to absorb and desorb SO2.Especially at 298.15 K,80% EGW(volume fraction) presented the strongest capability to absorb and desorb SO2 in all EGWs.The interaction mechanism of dilute SO2 with EG and EGW was mainly studied by means of modern spectroscopic technologies.When volume fraction 80% EGW is used to absorb SO2,UV,FTIR,fluorescence spectroscopic results show that SO2 can interact with EG by hydrogen bonding and S…O ligand interation which are weak,but benefit the absorption and desorption of SO2.
