Aims: This study aimed to eliminate metallic contaminants from drinking water by using
electrospun bi-layered microfiber membranes.
Background: Fast industrialization triggers environmental pollution. Heavy metals like silver, lead
and aluminum are the major contaminants that are extremely toxic and accumulate in biological tissues
through the food chain and cause a health hazard. Electrospinning is a promising technique
among other conventional techniques of removing these metals from drinking water. Electrospun
membranes possess suitable properties for microfiltration purposes. In this study, to fabricate electrospun
membranes, polycaprolactone (PCL) and zeolites were used as materials. PCL polymer is biocompatible
and biodegradable, and zeolite is microporous, which is good for filtration or molecular
Methods: Using the electrospinning technique, PCL, PCL/zeolite, PCL and PCL/zeolite bi-layered
electrospun membranes were fabricated. The properties of the membranes were evaluated using different
techniques. The performance of the membranes was tested by filtering Aluminum (Al) present
in drinking water.
Results: Scanning Electron Microscopy (SEM) and energy dispersive X-ray (EDX) analyses confirmed
the removal of Al using the membranes. ICP-OES results showed more than 90% of Al removal
using PCL and PCL/zeolite electrospun membranes.
Conclusion: These membranes are non-toxic and biodegradable and have the potential to be used for
