Water-soluble carboxymethyl chitosan (WSCC)-modified single-walled carbon nanotubes (SWCNTs) provide efficient adsorption of Pb(ii) from water.

ABSTRACT: Nanocomposites play a key role in the removal of toxic metal(loid)s from environmental water. In this study, we investigated the adsorption capability of water-soluble carboxymethyl chitosan (WSCC)-modified functionally oxidized single walled carbon nanotubes (oSWCNTs) for rapid and efficient removal of toxic Pb(ii) from water. The WSCC-oSWCNTs nanocomposite was prepared by an acid treatment of SWCNTs followed by an ultrasonic dispersion process using WSCC as dispersant. The morphology and chemical characteristics of the WSCC-oSWCNTs nanocomposite were further identified using various characterization techniques (i.e., transmission electron microscopy, TEM; scanning electron microscopy, SEM; Raman spectra; Fourier transform infrared spectroscopy, FTIR; X-ray photoelectron spectrosco
