Overview

This study demonstrates improved separation technology in membranes using graphene oxide and thin film composite layers.

Key Points

  • The optimized membrane achieved a permeance of 8.06 ± 2.31 L L m-2 h-1 bar-1 with 95.20 ± 1.54% dye rejection.
  • Utilizing interfacial polymerization with polyethyleneimine and trimethyl chloride enhanced membrane stability.
  • Characterization techniques included scanning electron microscopy and Fourier-transform infrared spectroscopy.
  • The charge-dependent separation mechanism improved rejection rates, indicating effective solvent purification.
