Water desalination and dyes separation from industrial wastewater by PES/TiO2NTs mixed matrix membranes

In this study, a simple and low-cost method is introduced to fabricate polyethersulfone/TiO 2 nanotubes (PES/TiO 2 NTs) membranes. The titanium dioxide nanotubes (TiO 2 NTs) are prepared by the hydrothermal method. The diameter of the nanotubes is ranging from 10 to 13 nm. TiO 2 NTs/PES mixed matrix...

Description
Summary:In this study, a simple and low-cost method is introduced to fabricate polyethersulfone/TiO 2 nanotubes (PES/TiO 2 NTs) membranes. The titanium dioxide nanotubes (TiO 2 NTs) are prepared by the hydrothermal method. The diameter of the nanotubes is ranging from 10 to 13 nm. TiO 2 NTs/PES mixed matrix membranes of different TiO 2 NTs % (0.18%, 0.35%, 0.53%, and 0.85%) are prepared by phase inversion method. The effects of TiO 2 NTs %, dye concentration, dye type, and contact time on the dye removal percent and flux are studied. The results showed that the removal % and permeate flux of the membrane for both desalination and dyes separation are enhanced through adding TiO 2 NTs. Also, these membranes show nanofiltration (NF)-reverse osmosis (RO) behavior at 200 mbar vacuum pressure.
