METHOD FOR MANUFACTURING CHITOSAN-BASED COMPOSITE PERVAPORATION MEMBRANE

摘要

The present invention provides a high permeability to water contained in the organic liquid mixture while forming an active layer by forming a active layer by forming a film using α-chitosan or β-chitosan obtained in nature and crosslinking with aldehyde or acid. The present invention relates to a method for producing a chitosan-based pervaporation composite membrane for separating an organic aqueous solution which can be separated at a high purity by showing a low transmittance.
