High purity ultrapure water is required in the electronics and pharmaceutical industries. Herein, we report production of high (18.5 L/h) by electrodeionization (EDI) technique a laboratory scale EDI unit (effective membrane area 24 cm × 6 cm) using polyethylene interpolymer based ion-exchange membranes. The also prepared process same two different types commercial membranes (Ionsep Fujifilm type II). resistance was 18.2 MΩ with at 25 V/cell pair applied potential, whereas Ionsep II final 15...

An anion exchange membrane (AEM) is applied for acid recovery through the diffusion dialysis (DD) process. However, a specially designed AEM required to achieve high coefficient of (UH+) and separation factor (S). The design our metal ion based on optimization water swelling, structural stabilization (cross-linking), introduction cationic moieties where delocalization charge in ring system (imidazole) possible. Based above design, herein, preparation cross-linked using...

Tuning of hydrophobicity, water uptake, and size the ion channel is very crucial for monovalent anion-selective membrane (MASM) preparation. In this work, we report preparation MASM from cross-linked polyacrylonitrile-co-polyvinylimidazole (PAN-co-PVI) copolymer. The copolymer was in situ quaternized using polyacrylonitrile-co-polychloromethylstyrene (PAN-co-PCMSt) as cross-linker. benzyl chloride moiety (Ar-CH2Cl) PAN-co-PCMSt reacts with imidazolium nitrogen PAN-co-PVI provides a positive...

Abstract Three types of silver/polymer nanocomposite films were prepared: (1) silver/polymethyl methacrylate, (2) silver/polystyrene, and (3) silver/polyt‐butyl methacrylate by mixing colloidal solution functionalized Ag nanoparticles with pre‐made polymers. The are randomly dispersed into the matrices. desired surface functionality nanoparticle was achieved using specific amphiphilic block copolymer (specific hydrophobic part) as stabilizer. stability in these host polymer matrices...

We report the preparation of a novel cross-linked anion exchange membrane (AEM) from poly(acrylonitrile)-co-poly(2-dimethylamino)ethyl methacrylate (PAN-co-PDMA) copolymer by quaternizing DMA moieties followed cross-linking –CN groups. This process avoids use carcinogenic reagent, chloromethyl ether (CME) which is widely employed for chloromethylation reaction in AEMs. Key parameters were evaluated via electrodialysis (ED) during water purification and revealed that containing 28 wt% PDMA...

We report the preparation of a new type anion exchange membrane (AEM) from random terpolymer poly n-butyl acrylate (PnBA), polyacrylonitrile (PAN) and poly(2-dimethyl aminoethyl)methacrylate (PDMA) through quaternization cross-linking. Moderate amounts hydrophobic soft PnBA (ca. 18 wt%) in considerably influenced electrochemical properties desalination performance membrane. Standardization experiments revealed that (AEM-2) prepared containing wt% PnBA, 50 PAN 32 PDMA exhibited low power...
