Abstract

This study focuses on to the change of the execution of polyamide (PA) thin-film composite (TFC) reverse osmosis (RO) membrane utilizing surface alteration by MgSiO3 nanoparticles.

This has been an expert by means of holding of the practical grafting of PA layer with magnesium silicate nanoparticles (MgSiO3) in the presence of 2-acylamido 2-methyl propane sulphonic acid (AMPS) as condensing monomer.

To confirm the presence of MgSiO3nanoparticles and to inspect the morphology of the TFC nanoparticles layer SEM, FT-IR, XRD, TGA and DMA analysis were used. The outcomes demonstrated that the AMPS are effectively joined on the TFC film surface with an upgrade in thermal and mechanical decencies contrasted with pristine TFC layer.

Besides, the contact angle estimations demonstrate an increase in the hydrophilicity of the thin film surface by the addition of nanoparticles. The water flux and salt rejection of the modified membranes were 25 L/m2 h and 95.5%, respectively.
