Polyaniline-lignosulfonate (PANI-LS) nanocomposite was prepared via an unstirred polymerization by using lignosulfonate (LS) as dispersant.The morphology
structure and properties of the PANI-LS nanocomposite were characterized by using scanning electron microscopy
transmission electron microscopy
FTIR
UV-vis spectra and wide angle X-ray diffraction.Moreover
the silver ions adsorbability of the PANI-LS nanocomposite was examined.The maximal sorption capacity of silver ions onto PANI-LS nanocomposite was up to 500 mg·g-1 at initial silver ion concentration of 0.03 mol·L-1.The product of PANI-LS nanocomposite after sorption was investigated by transmission electron microscopy and wide angle X-ray diffraction.The results showed that silver nanoparticles with diameters of 2—7 nm were homogeneously dispersed on the surface of the PANI-LS nanocomposite after sorption.This indicated that the PANI-LS nanocomposite possessed reactive adsorbability for silver ions.
