  7. Abstract:
  8. This study aims to investigate polysulfone (PSF) hollow fiber mixed matrix membranes (MMMs) properties containing Uio-66-NH2 and Mil-125-NH2 nanoparticles, groups of metal-organic frameworks (MOFs), for hemodialysis application. The nanoparticles were synthesized, and the membranes were produced by the phase inversion method. Membranes characterization conducted by ATR-FTIR, FE-SEM, EDX, TEM, and AFM was confirmed the presence of MOFs nanoparticles. Also, the evaluation of specific surface area of nanoparticles was done by BET. The water contact angle (WCA) results indicated the improvement of MMMs hydrophilicity, enhancing the pure water flux from 46.8 L/ m2h for the pristine membrane to 76.7 L/m2h for M4. Also, the fouling resistance of all membranes was remarkably, and bovine serum albumin (BSA) adsorption of modified membranes was lower than the pristine membrane. Urea and creatinine were cleared significantly for modified ones, and all membranes showed BSA retention of more than 93%. A comparison between MMMs that contained Uio-66-NH2 and Mil-125-NH2 showed that the former had had a better effect on the performance. M4 was selected as an optimum membrane, which showed the highest water flux, lowest fouling resistance, high porosity, lower BSA adsorption, and acceptable clearance percentage for urea and creatinine in addition to BSA retention of 94.2%.
