Synthesis of Nanocomposite (CAU-10-H) Thin-Film Nanocomposite (TFN) Membrane for Removal of Color from the Water

Abstract

In this study, all synthesized nanocomposite (CAU-10-H) samples were characterized by Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), and Fourier-Transform Infrared Spectroscopy (FTIR). The Nanofiltration (NF) membranes were constructed by interfacial polymerization of 1,3,5-benzenetricarbonyl trichloride and Piperazine using different loadings of (CAU-10-H) (0.250, 0.50% wt.). The removal of color from water by membranes with solution filtration showed that the membrane containing 0.50% wt. of the nanocomposite (CAU-10-H) had the best performance. The removal of color from water by flux rejection of the Thin-Film Nanocomposite (TFN) membrane was 25.45 L/m²·h, and Tirmethylcyclohexan-1-one rejection was 99.35% at 6 bar.
