Abstract

This study explores a laser-ablated mixed matrix membrane (MMM) for advanced water purification, composed of polyvinylidene fluoride (PVDF), cerium dioxide (ceria), and polyimide. Through laser ablation, we engineered a highly efficient MMM with exceptional water treatment capabilities. Extensive characterization studies assessed the MMM's physicochemical properties, morphology, and performance. Significantly, laser ablation induced a graphitic nature in the polyimide, doubling its adsorption affinity for heavy metal ions compared to conventional MMMs. Ceria serves as a catalyst within the PVDF/Ceria/Polyimide MMM, enhancing organic contaminant degradation through redox reactions and bolstering overall water purification performance. Moreover, ceria enhances membrane stability and fouling resistance, ensuring sustained heavy metal removal and water treatment efficacy. The laser-induced graphitic transformation of polyimide further augments heavy metal pollutant adsorption. This innovative approach holds promise for sustainable water treatment, with broad applications in environmental remediation and water resource management.
