| Summary: | In this study, silver nanoparticles (AgNPs) were encapsulated within porous metal-organic frameworks of ZIF-8 (ZIF-8/AgNPs), which were subsequently incorporated into electrospun nanofiber composite membranes composed of polyacrylonitrile (PAN). The obtained nanocomposite membranes were characterized using SEM, FT-IR, XRD, EDS and BET analysis. The potential application of the synthesized PAN-ZIF-8/AgNPs nanocomposite nanofibers for the removal of Cu (II) and Cd (II) ions was investigated through both adsorption and filtration The research investigated and optimized multiple adsorption parameters, including sample concentration, sample volume, sorbent quantity, pH, extraction time, and the reusability of the sorbent. The sorption process was most accurately described by the Langmuir isotherm model and the pseudo-second-order kinetic model. Additionally, the nanofiber composite was evaluated for its antimicrobial properties, demonstrating efficient antibacterial activity. The maximum adsorption capacity was gotten approximately 76.34 mg g−1 for Cd (II) and 79.36 mg g−1 for Cu (II) after 40 minutes of exposure. The study further investigated the effects of ZIF-8/AgNPs dosage in the nanofibrous membrane, metal ion concentration, and nanofiber thickness on metal ion removal and water flux. The method’s applicability was assessed by analyzing analytes in various real samples, suggesting that the prepared membrane holds promise for potential use in water purification systems. |
