Randomized trial demonstrates efficient Cd2+ removal in wastewater using enhanced nanofiltration membranes, suggesting significant improvements over traditional methods.
Key Points
The research aims to develop a composite nanofiltration membrane to enhance the removal of Cd2+ while ensuring high permeability and stability.
Developed membranes by incorporating NaY zeolite into electrospun PVA nanofibers on a PVDF substrate.
Crosslinked the PVA matrix with epichlorohydrin to enhance structural integrity.
Evaluated membranes for Cd2+ removal efficiency at varying concentrations and conditions.
Optimized membrane (MNaZ 5) achieved a permeation flux of 27.3 L/m2·h, a ∼100% increase from the control membrane (12.6 L/m2·h).
Membrane demonstrated 98% Cd2+ removal at 5 mg/L initial concentration and pH 9.
Enhanced thermal stability and antifouling performance observed in modified membranes.
