• This study reports the fabrication of mixed matrix membranes (MMMs) using immersion precipitation phase inversion for promising application in desalination of dye solutions. Aromatic poly­(m-phenylene isophthalamide) is used as the polymer material, and the metal–organic framework MIL-53­(Al) is added to develop integrally skinned asymmetric membranes. Successful dispersion of MIL-53­(Al) particles into the membrane-separating layer is confirmed by scanning electron microscopy. The optimum performance of the membranes is obtained at 0.5 wt % MIL-53­(Al) concentration. In particular, the M-0.5 membrane is planned for use in separating dye/salt aqueous mixtures. It is observed that the M-0.5 membrane has a rejection for NaCl and Na2SO4 below 11% and 37%, respectively, in mixed salt/dye solutions. Additionally, the M-0.5 membrane is found to have a rejection rate of 83.9%, 98.3%, and 99.8% for nitroso-R salt, xylenol orange, and ponceau S, respectively, in mixed Na2SO4/dye solutions. The rejection rate for Na2SO4 is lower than that of some commercial nanofiltration membranes (NF90, NF270, and DK). The membrane is promising for dye desalination in industrial-scale applications.
