Absorption mechanism of SO2 in volume fraction 80% ethylene glycol aqueous solution
Pages: 11-14
Year: Issue:  9
Journal: Chemical Engineering

Keyword:  烟气脱硫气液平衡氢键S…O配位;
Abstract: 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298.15K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...
