This study investigates the efficient and recyclable use of polymer-based membrane materials in wastewater treatment, focusing on calcium-based montmorillonite (Ca-MMT), pyrrole (Py), polypropylene (PP). Through sodium activation, organic modification, intercalation, situ polymerization, polypyrrole/montmorillonite (PPy/MMT) was synthesized. A polypyrrole/montmorillonite/polypropylene composite (PPy/MMT/PP) then fabricated using melt compression coating techniques for pollutant adsorption. The modification by PPy examined, alongside morphology, composition, structure PPy/MMT/PP. membrane’s adsorption performance methyl orange Pb2⁺ evaluated, with a focus cyclic results showed that increased interlayer spacing from 1.23 nm to 1.74 enhanced its specific surface area 99.424 m2/g. exhibited improved wettability capacity, achieving removal rates 95.98% 88.48% Pb2⁺, following pseudo-second-order kinetics. demonstrated recyclability, maintaining adsorption/desorption over three cycles. work provides valuable insights technical support sustainable treatment membranes.
