Pervaporation of water/ethanol mixtures through polyimide based mixed matrix membranes containing ZIF-8, ordered mesoporous silica and ZIF-8-silica core-shell spheres

摘要

BACKGROUNDPervaporation (PV) is a prospective industrial process for the separation of liquid mixtures such as azeotropic and close-boiling point. PV efficiency depends mainly on the properties of the membrane used. Hence, designing a membrane structure with high permeation rate and separation factor is an important issue.
