Phosphorus (P) recovery from wastewater is essential for eutrophication control, water reuse initiatives, and recovery of this depleting non-renewable resource. Herein, a polyacrylonitrile (PAN) electrospun nanofiber membrane (ENM) was fabricated with akageneite (Ak), and modified with benzyldimethyldodecylammonium chloride (BDDA), a cationic surfactant, for phosphorus recovery from wastewater. We examined the influence of BDDA concentration on membrane properties, including fiber diameter, surface area, surface charge, and contact angle. Membrane performance was then evaluated using adsorption isotherms and kinetics, in the presence of competing ions such as Cl^-, SO₄^2- and CO₃^2-, using synthetic wastewater and through a total of 7 adsorption-desorption cycles. Akageneite was found to be the only active ingredient responsible for P removal by the membrane. We observed that the increase in …
