Objective:
This project’s researchers will prepare nanofiltration membranes, functionalize them using different agents, including nanosized activated carbon, MXene nanosheets, and organic metal frameworks (MOF), and determine the membranes’ selective adsorption performance towards long and short-chained PFAS.
Progress Summary:
The MXene-TFN NF membranes showed enhanced PFOS rejection from 72% (bare TFC) to more than 96% (MXene TFN) while the water permeability was also increased from 13.19 (bare TFC) to 29.26 LMH/bar (0.025 wt.% MXene TFN).
Future Activities:
Functionalization of polyamide selective layer of TFN membranes by MXene nanosheets enhance the removal of PFOS and membrane permeability without sacrificing the membrane salt rejection.
