Abstract
En 中文
• In-situ growth and gelatin-assisted growth methods were used to prepare HKUST-1/PES adsorptive membranes. • Gelatin-assisted PES/J membranes showed 90.4% porosity and superior heavy metal removal. • Pb2+ removal reached near-complete efficiency due to electrostatic and π-complexation. • Adsorption kinetics followed pseudo-second-order and Elovich models (R2 > 0.9). • The Temkin isotherm model suggested energy-dependent adsorption interactions.
