Abstract Modified graphene oxide with 5,10,15,20-tetrakis‐(4‐hexyloxyphenyl) ‐porphyrin and palladium (II) (signified by GO-CPTMS@Pd-TKHPP) prepared as a novel antifouling polyether sulfone (PES) blended nanofiller membrane. The membrane efficiency has been analyzed such as pure water flux (PWF), hydrophilicity and antifouling features. By increasing of modified graphene oxide percentage from 0 to 0.1 wt.% in polymer matrix the PWF was incremented from 14.35 to 37.33 kg/m2.h at 4bar. The membrane flux recovery ratio (FRR) has been investigated by applying powdered milk solution, the FRR results indicated that the 0.1 wt.% modified graphene oxide membrane showed the positive effect on fouling behavior with Rir and FRR value 8.24 and 91.73% respectively. The nanofiltration membrane performance was assessed applying the Direct Red 16 dye rejection. It was demonstrated that the optimal membranes (0.1 wt.% modified graphene oxide) had notable dye removal (99.58 % rejection). The results are also verified by measuring the scanning electron microscopy (SEM), water contact angle (WCA) and atomic microscopy analysis (AFM).
