Abstract
A novel polyvinyl chloride (PVC)--based membrane incorporating magnetic silica core-shell nanoparticles (CoFe2 O4 @SiO2 ) was developed for efficient oil-water separation. The CoFe2 O4 core enhances magnetic functionality, while the SiO2 shell improves hydrophilicity and nanoparticle dispersion. Characterization techniques confirmed structural integrity and uniform distribution. Performance evaluation demonstrated over 97 % oil rejection for emulsions up to 1200 ppm at 6 bar, with a 270 L/m²·h permeation flux and strong antifouling properties over multiple cycles. Enhanced mechanical stability was also observed. These findings highlight the potential of CoFe2 O4 @SiO2 -integrated PVC membranes for advanced wastewater treatment and industrial oil separation applications.
