Abstract
The adsorption of xylitol residue in 200mg/L of Cr(VI) solution at different ionic strength was studied. Results show 97-99% of Cr(VI) can be effectively adsorbed when Ca and Na ion concentration was ten time of Cr, and the adsorbing ratio decreases with the increasing of Ca and Na concentration, indicating the competing adsorption of Na and Ca was not strong enough to reduce the adsorbing ability of xylitol residue greatly. Zn can reduce the adsorption ability of Cr when its concentration is only 1/10 of Cr concentration, and the adsorbing ratio decreases with the increasing of Zn ion indicating the competition effect of Zn with Cr. Cr concentration can not be determined accurately when Cu ion exist. Other determination method should be applied.
