Today, utilizing new technologies for heavy metal removal and water quality improvement is essential in combating environmental pollution caused by heavy metals. Polymeric nanofibers are widely used in the water treatment industry due to their high surface-to-volume ratio, three-dimensional structure, suitable mechanical properties, good pore connectivity, chemical potential, and high filtration performance at the nanoscale. In this study, thermoplastic polyurethane (TPU) and polyacrylonitrile (PAN) polymer nanofibers were prepared using electrospinning to investigate the removal of nickel and iron metal ions. Scanning electron microscopy revealed that a voltage of 10 volts and a distance of 15 cm, with a TPU/PAN polymer ratio of 70:30, were optimal for fiber production. The reaction between these polymers was analyzed using Fourier transform infrared spectroscopy (FTIR). The results demonstrated that increasing the amount of polyurethane in the polymer composition to a 70:30 ratio increased the contact angle of the droplet with the absorbent surface by 40.10°, compared to polyacrylonitrile with an angle of 21.49°. The findings indicated that the TPU:PAN adsorbent with a 70:30 ratio achieved a nickel absorption rate of 45.8% and an iron absorption rate of 33.18% under optimal pH and time conditions..
