ABSTRACT
In this paper, the
adsorbent for the removal of hexavalent Cr (Chromium) from aqueous solutions
has been prepared by modifying chitosan composite with EP (Epichlorohydrin) or
GA (Glutaraldehyde). The modified cross-linked chitosan was characterized by
SEM (Scanning Electron Microscopy) and FT-IR (Fourier
Transform Infrared Spectroscopy). Batch adsorption experiments were carried out
to evaluate the adsorption of Cr(VI) by the cross-linked chitosan
under different conditions. Furthermore, the sorption mechanism of Cr(VI) by the cross-linked chitosan was investigated by applying Langmuir and
Freundlich isotherm equations to the data obtained. The concentration of Cr in
solution was determined by ICP-MS
(Inductively Coupled Plasma Mass Spectrometry). The cross-linked chitosan can
be an efficient sorbent for Cr(VI).
