Abstract
A Na-cellulose adsorbent was prepared by treating Sigma S-5504 cellulose with 2M NaOH and examined the adsorption behavior between metal ions and Na-cellulose in aqueous solution with batch method. Considering ion exchange capacity of Na-cellulose, the adsorption ratio of the Na-cellulose to metals charge equivalent indicated that the adsorption result from ion exchanging between metal ions and Na-cellulose. The enthalpy for the metal adsorption on the Na-cellulose was calculated to -18kcal/mol, which value was compared to those of carboxymethylcellulose(CMC) and Dowex 50W-X8, these result suggested that the adsorption on Na-cellulose resulted from ion exchange adsorption.
