摘      要：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 ***,the sorption mechanism of Cr(VI)by the cross-linked chitosan was investigated by applying Langmuir and Freundlich isotherm equations to the data *** 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).
