Abstract: This study presents desorption of Cr(VI) ions from chitosan by various eluants (dilute mineral acids and organic acids). A maximum of 88% of Cr (VI) was desorbed from metal loaded chitosan with 0.1 M H2SO4 without any physical damage to adsorbent. Numerical optimization has been carried out by a central composite design (CCD) in response surface methodology (RSM). Chitosan was regenerated by successive washing with deionised water many times until a neutral pH was obtained. Regenerated adsorbent/chitosan was dried and used to initiate another cycle of sorption and desorption. Absence of noticeable change in adsorption capacities of reused adsorbent confirms reusable potential of chitosan.
