Abstract
The presented study provides a possibility to create ultrafiltration (UF), polyacrylonitrile(PAN)/butadiene-acrylonitrile elastomer (BNR)/N,N-dimethylformamide (DMF) membranes. Influence of different concentrations of the elastomer on the formation of a more porous structure was studied and compared with that observed using membranes made of polyacrylonitrile. Specific influence of copper ions in a solution of polymers on the formation of an asymmetric selective layer was also monitored. The study was conducted to prepare membranes with high efficiency in emulsion and colloidal systems separation.
