Abstract

This work presents the preparation of homogeneous anion exchange membrane (AEM) based on quaternized polyvinyl chloride (PVC)

via

straight forward quaternization of PVC with 1-methylimidazole (

-MI). In particular

the preparation avoids the use of toxic chloromethylation. The optimized AEM PVC-

-MI-5 shows ion-exchange capacity (IEC) and transport number of 2.89 mmol·g

–1

and 98.4%

respectively. The water uptake and swelling ratio are 4.24% and 0.21%

lower than the commercial AEM JAM-5 (4.87% and 3.33%). The NaCl removal ratio

current efficiency and energy consumption of the as-prepared AEM were 98.38%、55.8% and 5.1 kW·h·(kg NaCl)

－1

respectively

comparable to commerical JAM-5(93.0%

55.2% and 4.6 kW·h·(kg

NaCl)

－1

). The cost-effective PVC and relatively good performance are suggestive of the potential electrodialysis application.
