The nanofiber membranes prepared by electrospinning method attracted the attention of researchers in field pollutant treatment due to their ease manufacture, efficient performance and removal. Some these lack possibility reuse low efficiency high regeneration cost. In this paper, we were able prepare from polyacrylonitrile (PAN) PAN/TiO2 adding different ratios (5,10 15) wt% TiO2 respectively. ...
