- Iron nanoparticles coated with ionic choline-chloride liquid were used to improve the hydrophilicity and flow rate through the polyethersulfone (PES) membrane. Choline chloride as a modifier was used to obtain the highest water flux by increasing the hydrophilicity of the PES membrane. Changes in membrane structure and morphology were analyzed using FTIR, contact angle, porosity measurement, BET, TGA, DSC, and SEM images. Membrane clogging was measured in the presence of BSA. To evaluate the removal efficiency, Acid Orange 7 dye was used. Suitable removal conditions were obtained by Design-Expert software using a CCD model at optimum pH 6.7 and temperature of 33.9 °C by the DOE method (removal of 97.6%). Iron/choline chloride nanocomposite increased the PES membrane's hydrophilicity and fluid flow rate. Also, the membrane modified by iron/choline chloride nanocomposite removed the sample contaminant from the fluid environment under optimal conditions.
