title: Preparation of novel poly(vinyl alcohol)/SiO(2) composite nanofiber membranes with mesostructure and their application for removal of Cu(2+) from waste water.
abstract: Novel mesoporous poly(vinyl alcohol)/SiO(2) composite nanofiber membranes functionalized with mercapto groups with diameters of 300-500 nm have been fabricated by a sol-gel electrospinning process; they were highly effective at absorbing Cu(ii) ions from waste water. These nanofiber membranes could be regenerated through acidification.
