摘要：

Novel mesoporous poly(vinyl alcohol)/SiO2 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.
