Abstract

The main goals of this research endeavor are to enhance the hydrophilic properties and water permeability of a nanofiltration membrane. This is achieved by incorporating a Zeolitic imidazolate framework (ZIF-8) layer that has been stabilized utilizing a redox-grafted methacrylate hydrogel. The decision to use polyacrylonitrile (PAN) as the substrate material was motivated by its intrinsic hydrophilic properties, which contribute to its ability to resist fouling and promote water permeability. The shift of the surface from hydrophilic to superhydrophilic was confirmed using physicochemical evaluations, including scanning electron microscopy (SEM) and contact angle measurements. Hydrolyzed Polyacrylonitrile Zeolitic imidazolate framework grafted (HPANZifG) membrane exhibited a remarkably high-water flux of 82.3 L/m2 Bar hour, which is an achievement of notable significance. This study makes a valuable contribution to the advancement of nanofiltration technology by proposing potential solutions to the challenges faced in the field of water purification and treatment.
