Abstract
Novel composites of succinic anhydride modified multi-walled carbon nanotubes (MWCNTs), that is, MWCNTs-NC, encapsulated in macroporous poly(vinyl alcohol) (PVA) have been successfully developed with excellent Pb2+ and Cu2+ adsorption performance. It was found that nearly 100% of Pb2+ and 72% of Cu2+ could be removed by PVA/MWCNTs-NC at a wide pH range. It was revealed by Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy that the adsorption mechanism was mainly the chemical binding that occurred between functional groups derived from succinic anhydride and metal ions. Moreover, adsorption experiments were conducted in the fixed-bed continuous-flow column system to further evaluate the potential application of PVA/CNTs-NC for heavy metal ions removal.This publication has 33 references indexed in Scilit:
