摘要：

Polyvinyl alcohol/polyetherimide(PVA/PEI) nanofibers were fabricated by electrospinning. Sub-sequently, 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 appearance. 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.
