Abstract
Poly vinyl chloride and cellulose triacetate are the most extensively used and studied base polymers for preparation of polymer inclusion membranes used
in water purification. However, their instability under extreme conditions has brought about the need to explore other base polymers that can overcome such
limitations. In this study we investigated polysulfone as an alternative base polymer that could possibly withstand harsh environmental conditions and have
good transport efficiency towards metal ions. Polymer inclusion membranes were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier.
Chromate was used to study the extraction efficiency of the membranes. The optimal composition ratio for the membrane that gave the highest extraction efficiency
of chromate from solution
