Abstract:

Polyvinyl alcohol/polyetherimide(PVA/PEI) nanofibers were fabricated by electrospinning. Subsequently, the nanofibers were functionalized with carbon disulfide to form polyvinyl alcohol/dithiocarbamates(PVA/DTC) nanofibers with higher adsorption capacity for heavy metal ions. The adsorption performance of PVA/DTC nanofibers for lead as well as the crosslinking and functionalization reaction PVA/PEI were investigated. The experimental data show that the fibers have diameters in hundreds nanometers and good appea-rance. The microstructure of nanofiber almost kept unchanged after crosslinking process and functionalization. The PVA/DTC nanofibers with good regeneration power possess much rapid adsorption and higher adsorption capacity. It is potential adsorption material for efficently removal heavy metal ions from waste water.
