Abstract
This research enhances polyamide membrane desalination performance by chemically tuning the active layer using Boc-protected ethylenediamine (EDA). One EDA amino group is Boc-protected, allowing the other to participate in interfacial polymerization (IP) with meta-phenylenediamine (MPD) and trimesoyl chloride (TMC). Subsequent Boc-deprotection generates hydrophilic ammonium groups, improving desalination. The MPD-TMC-EDA-Deboc membrane (Boc-deprotected) showed 98 ± 0.5% salt rejection and 25 L m⁻² h⁻¹ permeate flux (25% increase over the control). Seawater nanofiltration showed 97% rejection and 23 L m⁻² h⁻¹ flux. Enhanced antifouling was also observed.
