摘要
基于石英晶体微天平(Quartz Crystal Microbalance,QCM)技术,建立了一种测定气体在离子液体(ILs)中基本热力学参数的方法.测定了5种可挥发有机物(VOCs)在6种咪唑类离子液体中的亨利常数,并对可能的作用机理进行了探讨.结果表明,QCM技术可以作为研究离子液体溶解性和作用规律的有效方法.
A convenient method to measure the solubility and thermodynamic properties for ionic liquids （ILs） towards gases under atmospheric pressure was developed based on the quartz crystal microbalance （QCM） technique. By using ILs as sensitive coating of QCM, Henry＇s constants of typical volatile organic compounds （VOCs） on five imidazole-based ILs were measured. The molecular interactions between ILs and VOCs were discussed based on the values of Henry＇s constants. Results indicated that the QCM technique could be an efficient approach for studing the solubility property and interaction properties of ILs.
