"ion-exchange membrane wafer improves electrodeionizaton's capture of p-coumaric acid from liquid mixtures using less energy... imidazolium ionomer, a polymer, and glued imidazolium membrane on top of resin wafer.,  reducing membrane need by 30%... also reduced interfacial resistance between membrane and wafer leading to increased rate of capturing p-coumaric acid, allowing smaller unit... 7X increased p-courmaric acid capture using 70% less energy"
