Abstract
Crosslinked chitosan can potentially be used as a sorbent for removing pertechnetate anion 9 9 textTcO 4 from aqueous solutions The chitosan was crosslinked with glutaraldehyde and prepared through chemical modification The sorbent was characterized by BETsurface area and potentiometric titration It was studied the influence of the contact time and the effect of pH on the sorption of pertechnetate anions The selectivity for crosslinked chitosan for different cations with concentration above 1 × 10−3 mol dm−3 was in the order Fe3+ Ca2+ Na+ Fe2+
