Abstract: |
|
A hollow fiber nanofiltration membrane is prepared based on coating a polyethersulfone support with sulfonated poly(ether ether ketone)(SPEEK). To optimize the nanofiltration properties of the composite membrane, several parameters were investigated including sulfonation degree, solvents, coating concentration, and post-processing temperature. It was found that for SPEEK-48 when using methanol as a solvent at the sulfonation degree and concentration of 0.55 and 1% gives satisfactory NF membranes. Treatment of dye waste water with this membrane demonstrated that the membrane can de-color the water while allowing the passing through of salts. This result is interesting in that it provides a new means for treatment of dye waste water and water systems alike. |
