HIGH PERMSELECTIVITY OF PVA/GA/CS-M+ MEMBRANE FOR DEHYDRATION OF ORGANIC SOLVENT AND PREPARATION METHOD THEREOF

摘要

Using GA as the crosslinking agent, the PVA/GA/CS-M⁺ pervaporation membrane having high mechanical strength can be readily obtained via blending the Ag⁺, Cu²⁺, or Fe³⁺-chelated CS precursor with PVA, performing excellent permeability and selectivity for the dehydration of organic solvents.
