Abstract:Negative charged composite nanofiltration(NF) membranes were prepared by coating sodium alginate(SA) solution onto porous polysulfone(PSF) or polyacrylonitrile(PAN) ultrafiltration membrane and further crosslinked with glutaraldehyde(GA),maleic anhydride.Effects of ultrafiltration membrane,catalyst,crosslinking agent,the concentration of SA on the performance were investigated.The composite NF membrane with excellent performance could be fabricated with SA concentration of 3wt%,GA concentration of 1wt%,sulf...
Keywords:sodium alginate  nanofiltration  polysulfone  membrane preparation
