【Abstract】 This paper describes the structure, properties and application of cycoldextrins, especially the application in PVA/CD pervaporation membranes. In the experiment, we used glutaradehyde to crosslink PVA with cyclodextrins, and prepared a new kind of crosslinked PVA/CD membrane. It turned out to have good pervaporation characteristics and it is valuable to be popularized.更多还原
