Preparation of Hybrid PVC/PAN Membrane and Application in Treatment of Papermaking Black Liquor
The hybrid of Poly vinyl chloride/polyacrylonitrile (PVC/PAN) membranes were prepared by wet phase-inversion technique, where PVC was used as a membrane material and dimethyl acetamide (DMAc) as solvents and PAN as additives, as well as its application in papermaking black liquor treatment was studied. The results showed that PVC/PAN membranes with an asymmetric mi-croporous structure, which was observed by scanning electron microscope (SEM). Water flux of PVC/PAN blending membranes could be up to 537.6L/m2·h, meanwhile, the retention of egg albumin up to 85.4％ at the content of PAN around 4wt％. In addition, the hybrid PVC /PAN membranes also had high removal rate of chromaticity (90.8％) and COD (83.2％ ) in the treatment of papermaking black liquor.
