Synthesis of chemically resistant polybenzimidazole membrane via green phosphoric acid crosslinking for efficient separation of selective flavonoids from citrus waste

This study introduces a chemically resilient Polybenzimidazole (PBI) thin-film composite membrane for organic solvent nanofiltration (OSN) based flavonoid fractionation of citrus waste, employing Phosphoric Acid (PA) as a mild, versatile, and low cost green crosslinker. The influence of crosslinking...
