Abstract
The effect of chemical structure of polyacrylonitrile -PAN- support membrane on the reverse osmosis performance of thin film composite -TFC- membrane was studied. Accordingly, PAN support membrane was hydrolyzed using alkaline at different contact times. The hydrolyzed support membranes were subjected to interfacial polymerization -IP- process using mphenylendiamine -MPD- and trimesoyl chloride -TMC- monomers. The structures of resultant polyamide TFC membranes were characterized by SEM analysis. Additionally, the performance of as-prepared TFC membranes was investigated through desalination of brackish water -2000ppm- at 7 bar. The results showed that hydrolysis of PAN support layer decreases both salt rejection and permeate flux of as-prepared TFC membrane when compared with non-hydrolyed support membrane. It seems that hydrolysis leads to increase hydrophilicity of support layer and as a consequence less extended polyamide layer may be formed. Therefore, it can be concluded that the hydrolysis of PAN weakens separation performance of PA/PAN TFC membrane.
