Abstract
In this paper, halloysite nanotubes (HNTs) and disodium-3-3′-disulfone-4-4′-dichlorodiphenylsulfone (S-DADPS) incorporated membranes designed to create a superior nanofiltration membrane. Interfacial polymerization technique was used for the fabrication process and key characterization tests such as contact angle, zeta potential, Scanning Electron Microscope (SEM), and Fourier Transform Infrared Spectroscopy Spectrum (FT-IR) were conducted prior to salt and dye performances tests. Two different dyes, setazol red and reactive orange of 100 ppm, and two different salt solutions, MgSO4 and NaCl of 1000 ppm were used to determine the performances. Consequently, MS-0.01 membrane was selected as best performed membrane, the addition of hydrophilic 0.01% of HNTs and 80% of S-DADPS monomer formed the best recipe to produce a thin film nanocomposite NF membrane. Lastly, pH and temperature resistance tests were performed to further investigate the performance losses of the selected membrane.
