Fabrication of polyamide membranes by interlayer-assisted interfacial polymerization method with enhanced organic solvent nanofiltration performance

Whether membranes developed for organic solvent nanofiltration (OSN) tend to be hydrophilic or hydrophobic? ── a review

“…Organic solvents contribute to 56 % of API materials and 80 % of pharmaceutical waste, emphasizing the need for their reduction to enhance environmental sustainability [ 143 ]. OSN can be used to concentrate many bioactive ingredients and API from solutions containing organic or aqueous solvents.…”
