Investigation of intrinsic bisphenol separation capacity of zeolitic imidazolate framework-8 based membranes

The present study deals with the synthesis of polyetherimide (PEI)-based membrane with zeolitic imidazolate framework (ZIF) nanoparticles as fillers by wet phase technique. The synthesized membranes were characterized based on their physical and chemical properties and were used to study the effective removal of Bisphenol A (BPA) from water. After the BPA removal with different membrane compositions, it was found that 1% PEI/ZIF-8 mixed matrix membrane gave maximum BPA rejection of 94.1% in comparison with other membranes. The flux recovery ratio of 0.92 was also found to be the highest for 1% PEI/ZIF-8 membrane which shows that this membrane has undergone the least fouling when compared to other membrane compositions. Overall, a 1% concentration of PEI/ZIF-8 membrane showed better characteristics and a maximum percentage of BPA removal was obtained.
