Managing heavy metal ions in wastewater is imperative due to their profound impacts on human health and the ecosystem. Membranes endowed with adsorptive features present a highly promising solution for efficient removal of contaminants such as cadmium (Cd2+), nickel (Ni2+), lead (Pb2+). This study focuses preparation membranes by immobilizing HKUST-1 metal-organic framework surface polyethersulfone (PES) from wastewater. was integrated onto membrane via gelatin-assisted growth in-situ techniques, further incorporated into PES polymer matrix. Comprehensive characterization these modified conducted using FESEM, XRD, FTIR, EDAX, contact angle analyses. The findings revealed that PES/J (gelatin-assisted growth) membrane, combination PES/I (in-situ exhibited superior efficacy removal. Notably, pure water flux gelatin-seed increased approximately 2.5-fold compared pristine membrane. demonstrated high fluxes ranging between 80 140 lit/m2.h.bar, whereas had around 25-50 lit/m2.h.bar. Furthermore, uniform dispersion crystals observed prepared method, which led efficiency 100% after min Cd2+ Ni2+ 60 Pb2+ ions. synthesis nanocomposite (ANMs) growth, mixed matrix approaches demonstrate potential
