Performance evaluation of supported ionic liquid membrane for removal of phenol

- Ionic liquid [BMIM][HSO4] was applied for phenol removal in a supported liquid membrane (SLM) for the first time.
- Up to 85% of phenol can be removed from wastewater by using the ionic liquid [BMIM][HSO4] with PTFE membrane filter.
- A stable SILM comprising of [BMIM][HSO4] and the hydrophobic PTFE support was achieved for over the experimental run of more than 24 h.
